It lookslike what you have is a scrip and not a function......run the file using F5 or through the run button or type the name of file in the workspace.

watershed is some mfile in your code and not a function. You are trying to execute it as a function which is why it is giving error.

If you want to execute watershed script just simply type

watershed

This will work fine

To convert watershed script to function, add this line at the start of watershed

function L = watershed(gmag)

assuming that it only needs gmag as input and L as output

Now because watershed changes from script to function you can call it by

L = watershed(gmag);
