Anyone can help me reverse this program?
This program contains the lower left side triangle to be 0, and I want the program to run on the opposite side on the upper right to be 0.
My program does not seem to be working properly. If anyone can help me reverse "0" in the matrix, that would be a great help in my studies.
Instead of (or next to) a picture, you should post your worksheet, or at least a worksheet that contains your specific problem. That will greatly help us help you.
Have you considered using the LU() function that is built into Prime?
I have been attaching my Prime file on the message for more than 1 hour, but it keeps on failing to attache the .mctx content type and keeps on getting removed.
No, I haven't tried the LU() function on the Prime. I wanted to play with the basics for now before using the shortcut LU() function.
You should not attach an .MCTX (template) file, but the .MCDX (worksheet) file...
And in case all else fails, you can zip the file and attach that archive.
It still says it doesn't match its file extension and has been removed. I already tried zipping it, the mcdx and the mctx, and it still fails.
I dont think it should be squared all the time. The last column is considered to be the constant. Was looking for a opposite side of my program, just to have the 3 "0" to be on the upper right side of the matrix.
I can do it manually, but I want to learn how to do the process by using the program of Mathcad Prime itself.
Found on the web the algorithm in C++ to calculate LU Decomposition of square matrices.
Converted side by side the C++ coding to Prime programming.
f_LU function gives the same answer as the web page example results.
It does not get the same answer as MathCad Prime LU function?.
It depends which L or U diagonal is normalized
The mathcad that I am using is 6.0. Is there any chance you could lower the version so I can see the continuation of the program?
Some members of the community know how to save back from 7 to 6. Trust they see this and can backdate it.
If you don't mind coding yourself here is the total program as screen shot.
Thank you for the great program. I'll try to analyze it and try to understand the program better. I'm still struggling with programming using mathcad Prime. I really appreciated the help.
