syntax error in the matlab code in image processing

Hi

Can anyone find the syntax error in the line:

>>function sketchrec('../TestCircuit/circuit1.jpg')

Error: File: sketchrec.m Line: 1 Column: 20 Unexpected MATLAB expression.

Parse error at '(' Invalid syntax at STRING

A line starting with

function

is the first line of a function definition. That means it must go in an m-file - usually it is the first line in the file. You can't define a function with this syntax on the command-line.

In a function definition, the thing in parentheses () must be the name of a variable (or more generally a comma-separated list of variable names). It can't be a string. When you call a function, you can give a string as an argument - but when calling a function you don't use the function keyword.

See the documentation for function.
