Why is my while loop infinite?

I'm not sure why this loop is running infinitely; shouldn't it end as soon as nVal is equal to the value of inputM?:
clear;
clc;
inpuTm = input('Enter the value for m: ');
nVal = 2;
pofN = [0,1];
while nVal <= inpuTm
pNext = 2*(nVal-1)+(nVal-2);
pofN = [pofN,pNext];
end
disp(pofN);

Yes, but neither nVal nor inpuTm are modified inside the while loop, so they remain unchanged and the loop either never executes or is an infinite loop depending upon the value of inpuTm.

How do I fix that? If I change pNext to nVal, it should be modified and is still not working.

'Pends on what you're trying to accomplish...probably incrementing nVal in the loop I'd guess, but you don't indicate what you expect the result to be, specifically.

nVal should increase by 1 until it equals the 'inpuTm' to create a vector 'pofN' with nVal number of values.

Why not use a for loop?
