Why it doesn’t work out?
显示 更早的评论
I have an image im=imread(...)/255 and If want to take the 2d fft of a color then I use this:
im=im(:,:,1);
im_fft2=fft2;
Now if I want to do it using haart2, matlab won’t let me saying that haart2 requires Wavelet Toolbox. Then it says something like Showaadon(‘WA’,’haart2’). What does it mean? How I’m supposed to use this? I have the newest version R2019a

You have to purchase the Wavelet Toolbox, or (probably) download a trial of it. Then you can use its functions.
Click on the telephone handset icon in the upper right corner of this page, and see if you can Download a Trial of the Wavelet Toolbox, or Contact Sales to purchase it.
