Hi I'm relatively new to Matlab.. I would like to know how to generate a matrix B that replaces all components of a matrix A (which is a 100x100 randomly generated matrix) lying between 2.9 and 3.2, by -1. I also tried using the for loop but it wouldn't work.
for i=1:100;
j=1:100;
if A(i,j)==2.9:3.2;
A(i,j)=-1;
end
end
Thanks a lot!!!
