Using imresize function for matlab coder

Hello, I am trying to use MATLAB coder to generate C code for imresize function as follows:

    % code
  function P = test_resize(I)
     %#codegen
     coder.varsize('I',[]);
     coder.varsize('P',[]);
     P = imresize(I,'scale',0.5,'Method','bilinear');
  end

However, the code generation readiness fails as shown in the following image:

any suggestions?

Code generation support was added for imresize in MATLAB R2015b:

What release of MATLAB are you using (the ver command will show you)?

You can search for imresize here:

to see any codegen specific considerations.

Hello Ryan, Thanks for your reply. The version was 2014a and I realized what you said that the support for imresize is added in the latest version 2015b which I am using now after updating. I can now generate the C code with no problems but when I am converting it to fixed-point operations I get an error readrding the imresize function that it cannot be converted to fixed-point operation. I thought that this conversion operation will overcome this issue. Is there is a solution for this as I am building this code for a fixed-point processor on an embedded platform.

Best regards
