Then once that is done, you need to take the part of it that starts from "function" and save it to the file timerCallback.m . have a peek here

Opportunities for recent engineering grads. first = 2; works for me, so it is morke likely that there is another syntax error in your code. functions can only be defined inside files whose first non-comment is "function" or "classdef".You need to rename your existing timerCallback.m file to something else such as timer_driver.m . This does not work if the strings are not the same length, because strings are arrays of characters, and to compare arrays with '==' they must be the same size. https://www.mathworks.com/matlabcentral/answers/279886-can-someone-help-me-with-parse-error-at-function-in-my-matlab-code

Forgetting the closing ' in the other syntax for a string results in an obvious error: >> A = 'hi ??? If you have too many END statements and more than one function in an M-file, MATLAB may give you a cryptic message about not formatting the functions correctly. Parse Error At Function Usage Might Be Invalid Matlab Syntax MATLAB will not return an error for this as it is not possible to know for certain that the aliasing of the function wasn't intentional. Matlab Parse Error At Eol You can choose to save fewer outputs than the function offers, but you cannot assign more variables than the function can output: >> A = [1,2;3,4] D = eig(A); %one output

How can I copy and paste text lines across different files in a bash script? Generally, MATLAB function names should be rendered to in lower-case letters (sin, not SIN) though sometimes MATLAB is flexible enough to recognize the equivalence (as seems to be the case for Hi Alec, I wrote x_0 instead of first and i took same error. this contact form Attempting to take a power of a nonsquare matrix results in the error ???

Browse other questions tagged matlab function or ask your own question. The correct syntax is >> if a == 3 >> end This creates no errors (and you can put anything inside the conditional you want).

In all three cases, the dimensions do not match. However, most engineering computations and formulas assume that the results from computations are real-valued. Often it is an indexing mistake that causes the terms to be of different size. Most of the syntax errors are not difficult to fix once you know what is causing them so this is intended to be a guide to identifying and fixing errors in
