Mathcad 14 does not solve matrix!

[jnik]

Hello there,

I really need your help. I am sure I wrote a good matrix and the formulas are not in red which means that the program accepts the variables and that the matrix is solvable. However, I get nothing when I try to solve it. Please find attached the picture:

It would probably be more useful to find the worksheet attached as well. 😉

One of the joys of debugging Mathcad from just pictures is that it is difficult to see certain typographical errors, such as a name subscript versus array index, or see what else may be interfering with a calculation.

Sorry, that's a really better idea. Here is the worksheet:

Also, this error occurs in another similar worksheet, only with bigger matrix. I really don't know what's wrong..

This doesn't solve for you?

As soon as it opened:

[jnik]

Omg. So there must be something wrong with my program. I can't believe this. I have been resolving it for hours

[jnik]

does it have anything to do with the split mathcad sheets?

I mean, maybe your program is modified differently?

When I open your sheet in the current release of Mathcad 15 M030 I get a similar result as Fred.

Do you have autocalculation turned on?

Of course it may be a corrupt installation of the program but it could also be a bug which was already fixed in a later release. Which maintainance release of MC14 are you using?

You wrote that you got "nothing" - what exactly do you mean by that? Have you tried typing Ctrl-F9 (recalc worksheet)?

does it have anything to do with the split mathcad sheets?

??? What do you mean by split MC sheet??

Your worksheet works fine in Mathcad 15 M030. Try to do the following:

• Enable automatic calculation ("Tools"-->"Calculate"-->"Automatic Calculation"). And/or use hotkey"Ctrl+F9" to recalculate your worksheet;
• Update your Mathcad 14 to Mathcad 14 M035 or Mathcad 15 M030 version - this is the latest service release for MC14/15.
