Q: Function difference in Scilab I am writing a function difference to find the error or the difference between the exact and the approximate solution by using the Euler function, this error is going to be a vector, but I receive this error message. Can you help me to figure out this problem? I am going to attach a screenshot of my code. Thanks in advance.enter image description here
