I'm trialling 9.0 just to get a feel for some image processing stuff, but already hit a problem: I've created a tiny matrix of grey scale values.I can write that out to a .bmp file using WRITEBMP (although I don't understand the "=0" syntax required for it to work?)I can read the bit map in again using READBMP and show the greyscale values again, so far so good. But how can I actually view the image as an image? As far as I can tell, there is no graph or plot function that can show a 2d plot of squares, each with a different shade of grey based on an 8 bit value.Neither does there appear to be another function to show the image (not the numbers) of a bitmap. I can insert a picture from file, but when I do this a.) it seems to show smoothing/interpolation between pixel values (where does this come from - if I open the image in windows Photos app it displays 9 pixels as expected ?!) and b.) it does not update if matrix values are changed. I am assuming that I am

I want my Mathcad Prime 3.0 sheet to auto populate using a different unit than the default unit system. For example I want all my answers to be in mm (millimeters) instead of m (meters). Can I change the default so I don't have to type "mm" into every answer manually?Thanks

Is there a known explanation for the next? I would think that the resulting units should be the same, but apparently not.This was with Prime 7.

I have a very simple problem as you can see below (file attached too.) I'd like to fit a line to measured data. There's something fundamental about minimize (and solving in general) that I don't understand and can't seem to find by searching through the literature. Changing TOL and CTOL have no effect. Help?  

Hello Everyone.How to write a symbolic evaluate Determinant code ?Thanks in advance for your time and help.Best Regards.Loi.

How do I get Mathcad Prime to give me colored coded results. If the result is Pass, return color in Green and if fails, Red? Please help  

When using Submatrix, is there a shortcut to specify the end of the column or end of the row?    

files created with MCAD 14 or MCAD 15 can be opened in MCAD 14, saved and re-opened in MCAD 15? 

Trying to plot a spring constant after measuring deformation due to applied weight Why is this scatterplot not working? Both M and S8mm have 10 values    

Good evening! There was such a problem.I'm a student. I have MathCAD Prime 8.0.0 installed. I used the trial version, and unfortunately it ended. It turns out that I need to purchase the paid version, right? And there is another problem, I'll be honest, to use this program, I created a new account every time. Now, when I receive a trial version, namely a license, a window pops up that I have received the maximum number of licenses for this program. What should I do?

The collapsed area contains the function NumberGenerator() that produces a new number for every supplied (integer) number. Three results are shown. Your task is to come up with a/the definition of the function such that it computes the (correct) value associated with 433 (and any other number in Z).   As you will find out, I've limited the function to just the three first input numbers with: Where the red placeholder should contain the code to implement the actual functionality. To not spoil the fun for others, I'll accept solutions in Prime or Mathcad as either one of: - the function NumberGenerator(), limited to the same input range, in a collapsed locked area, dated later than the timestamp above. The password should be the result of NumberGenerator(pw), and pw is supplied along. - submitted to me in a PM (in case you're limited to express).   Success!Luc  

Hi,I tried to calculate minimal value of the complex argument of a Transfer function through minimize function inside a resolution bloc. Mathcad indicates that there are no solution found, try to modified initial values or TOL or CTOL, but it does not help. I think that Mathcad does not find solution because the argument does not change, but manual calculation gives different values according constraints.Could you please help me to understand why the Mathcad do not understand the constraints? Thanks Christophe PS : Using Pime 4.0     

I have a current node locked license for Mathcad PTC 8.  I hear version 9 is out.  Although, I have a link for the trial version of Mathcad PTC 9 - I would rather use my license.  But, I can't seem to find a way to download the non-trial version of Mathcad PTC 9.    Is there a single link for this?

Hello everyone!I reworked a worksheet presented by a member of the community I think in 2018 related to the solution of a system of algebraic differential equations with a periodic sawtooth excitation function. I find quite different results depending on how the excitation function is defined. I wonder who's wrong. I enclose the version presented by the member (.mcdx) and my own (dae + 13032023.xmcd).I await your opinion.  

I'm curious if anyone has come up with a solution that is similar to using Find() w/in a Solve Block OUTSIDE of a solve block? I ask because I'd like to have the Find() ability to iterate/solve but use it as a custom function that I can call for N instances.There is a lot of value in Solve Block Find() but I have a case where I have a lot of inputs in V for which I would like to Find() solutions. I don't see this working just using a Solve Block.  

I am looking for the most efficient/quickest way to find the row containing two values in different columns of M. The function I am envisioning would be an alteration of 'lookup': lookup2(z1, z2, A, B).I have tried a few different solutions but was hoping for quicker performance. Using the masking method provided my  @Werner_E  and the efficiency of vectorizing demonstrated by @PEAH , I came up with a decent solution but was only able to cut the processing cost by ~30% when compared to Werner's FilterMlt function he helped me with not too long ago (solid function @Werner_E !). I am planning to use this lookup2 function a couple zillions times in processing data so I was hoping to cut processing time by much more!I also compared the time to run the built-in lookup function as a baseline which averaged ~0.15s @ N=10^5. I figure, looking up two values shouldn't be much more than one, max 2x 0.15 = 0.3s, but I am not able to achieve that.MCP wor

Supposedly my IT department has installed the Roark's E-book but it doesn't show up in Mathcad. Why?

Hello everyone!Not everyone knows that....for copy-pasting of formulas, text, images, on machines with low RAM, and with worksheet size 50MB and above, it takes quite a long time just for copying. A simple method is this: Click on the MATHCAD 15 Window pull-down menu, and then click on "tile Vertical" the worksheet and the "untitled" one will be tiled. Then select the object in the originary worksheet and drag it to the other "untitled" worksheet.Then click on "Undo" in order to restore the moved object to its original position.  The operation is immediate as well as the opposite action that is to past the object copied into another position of the originary file.I haven't tried it yet with M. PRIME. Greetings!

Hello everyone. Can someone help me to transform these files from xmcd format to mcdx format (for mathcad 5 prime?

I need to transfer my license (PTC Mathcad Express) to another computer, as I have to return the one I am currently using. I know that there is a procedure to do this, which requires the Product Code and the HOST ID of the new computer. I was provided with a license for my 30 days trial, but I can't find a product code within the file that I received. Can somebody please help? Thanks

Hello.why (solve) operation give me another result for the same equation with a simplified way for (MAD).thanks 

I am trying to display the results of a calculation using MathCAD PRIME 8's symbolics feature "explicit, ALL" The results are shown accurate to with 14 decimal places - which is way too precis for my purposes. I have been unable to fina a way to contol the precision of this display - Math Formatting appears to apply only to the final result. I attach two screenshots, one showing what I currently get from MathCAD and the other showing what I want. Does anyone know how to achieve this? Thanks in advance! Andrew

I have 2 ode's that I solve using odesolve. However, I can integrate one of them analytically. When I do this, I get the error message "Too many initial conditions" even though I only have one for the remaining ode. Or can I not include the integrated function in the solve block?

What is more correct - Mathcad or Maple (SMath) Mathcad Maple

Hi! I am experiencing an error that states: This variable is undefined, even though it is.What is the problem here?I am running Prime 8. /Frederik
