How to use for loop and ifelse condition with Nx1 matrix.

A:N x 1 matrix.

n = size(A,1)

for i = 1:n           % increment 1

if A(i,1) = 5         % Error: The expression is to the left....

A(i,1) = 1               % when A(i,1) = 5 , replace A(i,1) original value to 1.

Error message.

Error: The expression to the left of the equals sign is not a valid target for an assignment.

Do you know how to replace original values in a matrix to a specific value on the basis of comparision between matrix value and a value such as 5?
