Replace specific numbers in a matrix

2 views (last 30 days)
I am in a noob level right now. So, question might look silly. But here is it anyway:
I have a matrix of 10x10 with integer numbers. I need to find the numbers which are greater then 90 and replace it with 'inf'. I can replace those numbers with zero by using conditional operator. Like: A = A.*(A<90)
But how can I replace them with 'inf'? I know I can use 'for' and 'if-else'. But there must be more elegant way to do that I guess.

Lets say your matrix is called A, then
A(A>90) = Inf;
That simple :)
