clc,clear
prompt = 'Give a matrix of 4x4: ';
x = input(prompt);
for i=1:16
if x(i)<=0
disp('Error one of the numbers put in was either a zero or negative, Fix it and start over.')
if i~=1:16
disp('The matrix is not a 4x4 please start again and fix the error.')
end
end
end
disp(x)
Cause at the moment Im only allowed to do 4x4 or 4x5 or 4x6 i cant do 3x3 or 4x3 etc...
