I am trying to go from a 4x7 zero matrix, and change odd number indices in a matrix to 30 and even numbered indices to 45 using a loop. Does anyone know how to do this?

Why do you want a loop? And do you consider (2,3) even or odd? This is small enough that for 4x7 you could write out the intended output.

Since this seems like a homework question so I won't give the solution, but here is a hint. You can use mod() function to check if a number is even or odd.
And use for-loop to iterate over a matrix
M; % matrix
for i = 1:numel(M)
if mod(i, ???)
M(i) = ???
else
M(i) = ???
end
end
