MATLAB: How to replace all odd numbers with infinity using find()

findmatrix array

I have a code that looks like this: C = randi([100,200],1000,1000);
How would I replace all the odd numbers with infinity using the find() function. I read up on find but I am unsure how to replace just the odd numbers.
Thank you in advance

Best Answer

locations = find( Value_Is_Odd(C) );
where Value_Is_Odd is a function or expression that you write that takes in an array of values and returns a logical array of which entries are odd.
Hint: rem(), mod()
