Thread Subject: About polyxpoly

Dear all,
I am using MATLAB 2010B. My question is about polyxpoly function. My code reads data from Excel file. But everytime I get the following error:

??? Undefined function or method 'inputcheck' for input arguments of type
'char'.

Error in ==> polyxpoly at 39
msg = inputcheck('xyvector',x1,y1); if ~isempty(msg); error(msg); end

Error in ==> CAM_TraitementPercage at 276
    R3(i) =
    polyxpoly(RayonDiscret,AngleCoupeDiscret,MatEfforts{i,1}(:,5),Theta);

RayonDiscret,AngleCoupeDiscret,MatEfforts{i,1}(:,5),Theta these are my variables. I have checked them and they all exsist. I am not an expert and I couldn't figure out what I do wrong.
I am using a polyxpoly.m

Does my problem relates to a version of polyxpoly.m or to what?
Please help me about this problem if you have an answer.
Thank you for your time.

PS: If you need I can provide code also related data or more info. Thank you.

Hi Olcay,

It could be that your input to a function is supposed to be of type double but you are inputting a string. When you are using xlsread to read your data, you may want to make sure you convert them to double before using if they are not. If this doesn't solve your problem, I can take a look at your data and code.

Best.

The version of POLYXPOLY included with Mapping Toolbox in release R2010b
does not include this line of code. It appears you are using a much older
version of this function from an older release; you should not be doing so.
If you have Mapping Toolbox included in your installation you should use the
version of POLYXPOLY included with that toolbox.
