Hello

I want to reverse my image horizantally to see the propagation in the x-axis ( like in the figure 2 P_energy), I used Flip function but it didn't work in this case.

Any suggestion please.

Thank you in advance.

transpose if you have intensity data; permute if you have RGB data.

Thank you so much, It worked well.

Also , I want to change the background of the image in white to have a lighter image, Is it possible?

Thanks

You can set the figure property 'Color' -- though I would suggest that instead you create a uipanel within the figure, and make the uipanel the parent of the axes, and set the uipanel Color property . This will have the effect of changing the color only inside the uipanel instead of the entire figure.
