Matrix dimensions prime 3.1

[nchater]

Hello everyone,

I am working with Mathcad Prime 3.1, and I need to create a matrix 16*12, But I find that the maximum of rows to create is 12 and I need 16 in my case.

Is there a way to solve this problem.

Thank you so much

Best regards,

Nadia

You can add rows or columns under the Matrices/Tables tab.  Or, a shortcut for more rows is Shift-Enter, for more columns Shift-Space.

There is no problem in creating large matrices, even with millions of elements, It's just that the user interface for creating a simple matrix is limited to 12x12. But you can do as follows:

Now if you copy that matrix to the definition of yours, you can fill it up.

Success!

They must have figured that no-one is going to fill up a matrix larger than 12x12 by hand. They may be right. Generally you would have some kind of recipe or algorithm to define the matrix elements. Basically that's what I used to create the 21x21 matrix, by defining just the bottom-right element.
