Can anybody help me?

Good morning everyone,

I'm not really into Matllab and that's why I'm asking you to help me. I'm trying to create a for loop in which i multiply a matrix P by a scalar( the ith component of lambda) that changes for evey iteration. So i want to repeat this operation 19 times.

To be more clear:

lambda= 0.1:0.05:1; lambda is a row vector (1x19 double)

The matrix P is a 13x13 double

I began with something like this but I don't know how to continue:

for i=1:length(lambda)

Pprime(i) = P.*(lambda)

end

Thanks in advance

Change

 Pprime(i) = P.*(lambda)

to

 Pprime(i) = P.*(lambda(i));

 Pprime = bsxfun(@times, P, reshape(lambda, 1, 1, [ ]) % for newer versions use .* directly
