Importdata within a User-Defined Matlab Function

Hi Guys,

Suppose I have a function, called "myfun.m", and I want, amongst other things, an input argument to this function to be a data file (.dat), how would I do this?

I have already defined all the code for the function, and it works, but now I want it to be able to apply it to any .dat file I choose, rather than just the dat file specified within the function it.

I currently use importdata, so the use of this within myfun.m, would be great.

myfun(mydata,p1,p2,p3,...)

Where myfun contains the line:

M=importdata('mydata',1,' ')

doesn't work!

Any help would be much appreciated!

It doesn't work says nothing about your problem, please post the error message and more code.

You are passing mydata to importdata as a string literal (single quotes around the word mydata), so MATLAB is trying to open a file called "mydata", when you intend to load what is specified by the value of the variable mydata.

Remove the single quotes and you should be in good shape:

 M=importdata(mydata,1,' ')
