What is prime doing here???

[ptc-4735478]

attached is two version of a program (in prime 2.0 and mathcad 15) that is meant to do the same thing. The program is not exactly the same but it is strange enough that prime 2.0 can only numeric but not symbolic evaluate the answer. And sometimes, it is the other way around! But mathcad 15 can do it both way all the time!

I am utlizing the new function that return a row of a matrix in prime 2.0..is it the problem?? I am just a new user of mathcad and I can already feel what prime lacks...

Use the conversion utility in Prime.

It produces the correct program from the MC15 version.

I don't know what the problem is, but if you do as Michael suggests and convert the MC15 program it works fine. I suggest you start with the converted program, and modify it. When it stops working, you will know what caused it. If you do that, please let us know what you find.

somehow my converter does not know I have MC15. Do I have to install all mathcad version under the same file?

[MichaelH]

I think you need at least version M010 of MC15 for the converter to work.

What version do you have??

[ptc-4735478]

Mathcad 15.0 (15.0.0.436

I guess I dont have the latest version of MC15

This is a Mathcad 15 F000 release.

Here you can find the latest service release M020 of Mathcad 15: http://www.ptc.com/appserver/wcms/forms/index.jsp?&im_dbkey=41685&icg_dbkey=482

Please see the attached worksheet

somehow the symbolic calculator failed at the augment function!!

The program on the left and right are exactly the same....except one has augment at the end, which failed. Have to debug it line by line to spot the problem...anyone know what happens here??

[MichaelH]

This is what the converter produced.

[ptc-4735478]

Thank you for the conversion. The converted file work perfectly fine.

But now I have a different problem on augment. Please see my above post and the attached file

[RichardJ]

It's not the augment. It's what you originally guessed might be the problem: the row operator, with a transpose. I don't know why though, because they work fine if just applied to a matrix.

[ptc-4735478 · Accepted solution]

I find that if there is a line

A <--A

before using the row operator on a...then it can be transposed

This is the second time when I encounter a problem in programing where I have to do

A<--- A

before doing any operation on A...

But I never have to do this in mathcad 15!
