below is my shearlet code but error is coming.in 15th line unexpected matlab expression,can anyone help

% create image

A = rgb2gray(imread('C:\Users\HP\Desktop\steg\image.png'));

% shearlet transform

[ST,Psi] = shearletTransformSpect(A);

% inverse shearlet transform

C = inverseShearletTransformSpect(ST,Psi);

% plot results

subplot(2,2,1) imagesc('A') axis image off colormap(gray) title('original image')

subplot(2,2,2) imagesc(abs(ST(:,:,18))) axis image off colormap(gray) title('shearlet coefficients')

subplot(2,2,3) imagesc(Psi(:,:,18)) axis image off colormap(gray) title('shearlet')

subplot(2,2,4) imagesc(C) axis image off colormap(gray) title('reconstructed image')

Try this instead:

imagesc(A)

I cannot run your code. I have no reason at present to install the ShearLab software.

One problem is this (and similar) lines:

    subplot(2,2,1) imagesc('A') axis image off colormap(gray) title('original image')

Change them (and similar ‘lines’) to:

subplot(2,2,1)
imagesc(A)
axis 
colormap(gray) 
title('original image')

MATLAB has no idea what you want when you separate function calls and assignments by spaces only.

It is best to put each on a separate line.

However you at least have to put commas (,) between them, not spaces (unless the documentation for a particular function or command allows spaces between the command call and the argument).

thank you sir

As always, my pleasure.
