## HOW TO UNPACK MATRIC IN MATHCAD PRIME

Dear Everyone,

Could you suggest me how to unpack matric in Mathcad Prime?  (as PIC attached below)

Best regard,

While I would prefer writing a small program to do the job, here is a way doing it without programming.

I have chosen an ORIGIN aware approach, but as it seems you hae changed ORIGIN from the default 0 to value 1, you sure could replace ORIGIN by 1 in the expression.

Note, that using your original data the result would still be just a 4x4 matrix. You still will have to explain how you would derive that 8x8 matrix you are asking for. 8 REPLIES 8

Well that's a bug. You should ask yourself how that operation could result in a 4x1 nested vector. The answer is, "it can't". To get to the next part of your question, how to expand a 2x2 nested matrix of 2x2 matrices into an 8x8 matrix, the answer is "you can't". Where would all the extra elements come from?

My purpose, I want to show all number elements of matrices as Prefer Answer , can?

Richard already explained that the display after the inline evalution is wrong and thats a Prime bug.

If you write c= you see the correct structure.

I could understand if you ask for a 4 x 4 matrix with all 16 values unnested, but I also don't understand how you would calculate the 64 values of the 8x8 matrix you are asking for!! ## Re: HOW TO UNPACK MATRIC IN MATHCAD PRIME

OK, finally here are two ways to achieve the result using some programming. ## Re: HOW TO UNPACK MATRIC IN MATHCAD PRIME

Perfect 👌! These 2 methods
You go my point 😍😍😍 👍👍👍

Just for fun here is a third function doing the job.

Guess your 8x8 matrix was a mistake and you meant 4x4 👍👍👍
