Replacing array values which match a condition

Hello

It is easy to replace some element of a matrix meeting a condition by a constant number. lets consider a situation. For example if i have a 100*100 matrix of angles. I was to replace all the angle > 90 deg with 180-that angle. How can i acheive this ?

Thanks

Thanks a lot
