How can I solve "Undefined function or method 'IFFT_oversampling' for input arguments of type 'double'."?

Undefined function or method 'IFFT_oversampling' for input arguments of type 'double'.

x = IFFT_oversampling(X,N,L);

How can I solve this problem?

Answer 1

[Wayne King]

where did you get this function from?

 IFFT_oversampling

This is not a MathWorks' function, so if you have downloaded it from somebody or written it yourself, you have to make sure the folder (directory) that the function is in is on the MATLAB path.

For example, if you have the function saved in c:\myfiles, then

 >>addpath 'c:\myfiles'

You can also use

>>pathtool

to add the folder. Once you have added the folder, you should be able to enter

>>which IFFT_oversampling

and see that MATLAB recognizes the M-file.
