Hi, I need to convert matlab code into c++ code. I decide to use opencv to deal with the functionality of imagine processing. In my matlab code, I use the functions below to draw images.

           figure();
            subplot();
            imagesc();
            colormap()); 
            caxis();
            ylim
            xlim
            xlabel
            ylabel

Could anyone tell me which functions in opencv I should learn or use? thank you.

The first picture is what I get in Matlab, and I want get the similar result using opencv. All the data structures have been done. And the second picture is the code of using opencv to replace function imagesc, but I couldn't get result. I am a new learner to opencv, Could anyone help me solve this problem? Thank you. image description

well, colormap at least has a corresponding applyColorMap()

for the rest of it : you simply cannot translate matlab code to c++, or opencv code line-by-line.

there's a plot module in opencv_contrib, there are drawing functions and imshow()

-- just don't expect, that anyone there even vaguely tries to copy matlab interfaces.

Thank you for your answer. I also want to know which function could replace the function of imagesc. This function is important for conversion. And my parameter of imagesc is a [1933x362 double] matrix.

I think @berak was not clear enough. Trying to translate code exactly from matlab to OpenCV will never work. You can translate concepts, but both frameworks are so different in accessing data and such ...
