Matrix manipulation via for loop

The pressure matrix (p1) we were given is a 2d matrix 96 by 144. Here are the question instructions:
Use a for loop to convert the pressure in mb in the pressure array into pascals. Use the conversion given above to do so. Place the new data in a new pressure array called p1_pa. The array of p1_pa should be the same size as the p1 array. 1mb= 100Pa
Now, why they ask for a "for loop" instead of matrix multiplication (.*) I don't know. But when I'm working on this, I think the issue is the "for loop" isn't doing element by element operations, because it continuously overwrittes p1_pa, eventually spitting out just one scalar.
Thanks!

Result(k)=... (k)- k denotes loop iterator , saves result in each iteration forming a vector in the end
