RE: define the column and rows in a matrix

Is there a way of defining the number of matrix rows and columns just by say setting up a function? i.e. if I want a 5x5 matrix I can just type 5 and 5 in two functions and the matrix will auto generate

Does this do what you want?

If you are referring to a matrix with empty placeholders, unfortunately not.

yes, then you can enter your data. is the only way to add or delete lines is by clicking on the matrix tab again? if so thats pretty poor

So you are referring to Prime??

Try Shift-Enter and/or Shift-Tab to add rows and columns. (one of the very few things which are more convenient in Prime than in Mathcad).

Sure you can do that. But what do you mean with "just type 5 and 5 in two functions"?

Could it be that the command "matrix" is what you are looking for?

Otherwise you will have to provide an example of what exactly you are after.

So this seems to be Mathcad 15 or below?

And what exactly is it want you want to do? Obviously you know how to create a matrix with empty placeholders by typing Ctrl-M and you can add or delete rows and columns via Ctrl-M, too.

As Michael already said its not possible to create a matrix with empty placeholders via a command in a program and I honestly can't see any benefit if we would be able to do so.

But you can easily create any type of matrix using a function filled with any values you wish.
