Display an image in a UIaxes Matlab app designer

I want to display the image in a UIaxes , but the error is:

Expected input number 2, PARAM, to match one of these values:

Colormap', 'DisplayRange', 'InitialMagnification', 'XData', 'YData',

'Parent', 'Border', 'Reduce'

The input, '2', did not match any of the valid values.

              a = fix(num_int/2);
 
                for i = 1 : num_int
                    RMSE_map2 = RMSE(:,:,i);
                    RMSE_map2(~im_kidneys(:,:,i)) = NaN;
                    figure,imagesc(RMSE_map2,[0 0.8]) % please refer to the histogram to choose the range
                    colormap jet
                    colorbar
                    saveas(gcf,[dir_name3,'RMSE_slice_',int2str(i),'.jpg'], 'jpeg');
                end
                imshow('RMSE_slice_',int2str(a),'jpeg','Parent', app.UIAxes);

How can i modify this code?

Are you trying to show RMSE_slice_xxx.jpg ? (for e.g. int2str(a) = xxx)

You can try following command:

imshow(['RMSE_slice_',int2str(a),'.jpg'],'Parent', app.UIAxes);

‘imshow’ expects arguments like ‘DisplayRange’, ‘Colormap’ etc. In the code given the use of ‘int2str(a)’ does not match any of the expecting arguments.

To display an image on a “UIFigure” you can use the below code

I = imshow('Filename.jpg', 'Parent', app.UIAxes); 

In order to know more about what arguments can be passed to ‘imshow’ refer to the following link

Hope this Helps!
