How to replace numbers in a matrix with another number?

I am stuck with a problem. I have a 2D matrix, let’s say, m*n as the size of the matrix. I want to put the values whose magnitude is less than a given constant (a very small decimal number) as 0, but I want to avoid for loop in my code for this.

Is there any way to do this?

Thank you.

I guess from my understanding of your question that you just want to replace the values with 0 if their magnitude is less than a number.

Try the given below code. It is better than having for loop for this operation in MATLAB.

A=rand(6,5)
n=0.5;
A(abs(A)<n)=0
