Original question by Michael McGaha retrieved from Google Cache:
I received the error message "Error using sym/rref Too many output arguments."
Error in columnspaces (line 19)
[R, pivot] = rref(B);
---------------------------------
columnspaces is a function I created. I have no idea why I am receiving this error especially since I do [R, pivot] = rref(A); on line 17. Since both take in matrices as input, I am unsure as to why I am only receivng an error message on line 19. They are essentially the same thing, how does only one of them produce this error????

The one on line 19 has a symbolic input. The symbolic function rref does not have two outputs.

How are you calling the function columnspaces()? I guess you are trying to run it by pressing the big green button in the toolbar. You need to pass an input argument to columnspaces() otherwise, it will not recognize what is the value of 'A'. Run something like the following in the command window
columnspaces(A)
