Is there a way to add trailing 0s after they are inputted in MATLAB (ex turning 4 -> 4.0 or 4.00?) my code wont work unless the sigfigs match but i found rounding them in the matrix using M = round(M,4,"decimals") or M = round(M,4,"significant") just keeps it at the same integer value.
Thank you!

The number of trailing zeros displayed in the command window is unrelated to how much precision M actually has. We need a more full description (with code) of the problem you are encountering.

You have to use strings to control the number of decimals.
sprintf('%.1f', 4)
ans = '4.0'
sprintf('%.2f', 4)
ans = '4.00'
sprintf('%.6f', 4)
ans = '4.000000'
