Mathcad 14 does not solve matrix!

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:

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.

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..
