there is many ways to do it, you can for example assign i rows, j rows in a matrix of ones; then multiply by pi
x=ones(4,6)
y=x.*pi

Well, no, you don't HAVE to do it that way. In fact, I can think of at least a half dozen ways to solve the problem. Given that this is surely a homework problem, I would not supply those answer, nor would I have given a direct answer at all. Instead it is better to guide the person into solving it themselves.
another way; it means from the first to 4th row and from the first to 6th column.
mat(1:4,1:6)=pi
of course there is a lot of alternatives .. i will rephrase it

Creating matrices is one of the fundamental operations in MATLAB. Take a look at the links on this documentation page. A number of the functions included on that page will be of use to you, both for this particular assignment and as you work more with MATLAB.
a=zeros(4,6)+pi
a = 4×6
