how can I set double-value array input in a function?

Hello,

I want to create a function with inputs 2 arrays (with double values) and one value and i get the following message:

'Undefined function 'HighestPrice' for input arguments of type 'double'.

Any ideas?

Thank you.

This error message indicates that you have the function HighestPrice.m in a folder that is not on the MATLAB path.

Let's say you have this file in c:\mfiles. You have to add this folder to the MATLAB path.

Either

>>addpath 'c:\mfiles'

or use

>>pathtool

and add the folder.

If you have done it correctly, you can enter

>>which HighestPrice

and MATLAB will return the path to the .m file.

I have in my working folder. I checked it. However, while using the 'which HighestPrice' I get a message that the function was not found.

Then that folder is not on the path, or you do not have the function in the folder. One or both of those is true.

Enter

>>path

and look for that folder. Then go to the folder and make sure you have saved the function where you think you have.

Or the file is misnamed. It should be HighestPrice.m as noted above.
