error is shown:

Error: File: shottered.m Line: 1 Column: 8
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error.
To construct matrices, use brackets instead of parentheses.

What is line 1 of shottered.m?

image is a built-in function and that may be the problem -- it's expecting input arguments for the image. Don't use image as your variable name. Call it inputImage or something.
