MATLAB: Creating matrix with incremental values

Question

How can I create a matrix like

A=[1 2 3;4 5 6;7 8 9]

using loops?

Answer 1

using loops, you asked for.

mat1=[];
row_num=3; % Change the row number as per require
colm_num=3; % Change the col number as per require
count=0;
for i=1:row_num
 for j=1:colm_num
    count=count+1;
    mat1(i,j)=count;
end
end 
disp(mat1);
