MATLAB: How to create a Mupad symbolic variable as a matrix

matrixsymbolic variable

Hi,

Is it possible to create a Mupad symbolic variable as a matrix, only specifying the dimension but not the element?

I don't want the elements of the matrix variable to appear in my equation.

Thanks in advance!

Do you need to do this at the MATLAB level or at the MuPAD level?

Is there a particular data type that the matrix will hold (e.g., numbers only), or do you need a general symbolic matrix?

Which release do you have? If you have 2010b or later, you can do it, provided you assign specific dimensions: see the documentation for sym

That method is new for 2010b; before that you have to assign it a matrix of symbolic values, such as I show here

in the command line and look for symbolic math toolbox. If it's not in the list, then you would have to purchase it
