how to resize the image in matlab? not using resize function.

For example my matlab output image is (476 by 476) pixels and I want to resize it (512 by 512) pixels exactly. If anyone have an idea please share. Thanks

Use interp2 if you don't want to use resize .... resize also does the same in fact.

However, think carefully about which interpolation algorithm you wish to use.

Besides interp2, you can also use fft() to resample.

There is also imcrop()
