How to build a inverse matrix

[KPRO]

Hi,

I have a matrix (A). How to build the inverse matrix (A)? I am using labview 8.6

Thanks,

Use inverse matrix, I believe this is available in 8.6 too. http://zone.ni.com/reference/en-XX/help/371361G-01/gmath/inverse_matrix/

Hi KPRO,

that's the LV2009 style:

See the attached VI in LV8.6…

Edit: Here's the link into the LV8.6 help!

Simple stuff like this is usually much more quickly answered by looking at the LabVIEW help.

Help->type 'inverse matrix'

Thank you very much. It's working now.

Hi

Is it possible to use Linear Algebra functions in cRIO? while the cRIO is Linux based platform and it wont support dlls.

Thanks & Regards,

Hi Shree,

yes.

LabVIEW will tell you about unsupported function in two ways:

- you cannot find a function in the palettes when it is not supported

- the (RTEXE) build fails with an error message about unsupported functions

Hi GerdW,

thanks for the info. I tried to run a matrix function (Refer attached vi) in cRIO & Win10, the answers are different. When I run the Vi in PC, the output is TRUE and in cRIO, the output is FALSE. So, I gone through the sub vi's, i found there are different DLL functions for PC, RT target. I tried removing the Conditional diagram, but still getting the same result.

Is it any other way to replicate the same functionality as PC for RT target?

Whether cRIO supports DLL call functions? Because cRIO is Linux platform.

Thanks & Regards,

Shree

Replace the  "equal" with a "subtract" and add an array indicator to see how much it differs from zero. Maybe it's insignificant. Comparing DBLs is always problematic.

Hi,

I tried Subtract to find the difference. The difference is really high. I have attached the screenshot of it. I think the problem is with the DLL. Whether i can replicate the functionality AX = Y in Mathscript?

Thanks iun advance!
