Matlab square root of image
Web24 nov. 2024 · Two simple options: Theme Copy x^ (1/3) Or, Theme Copy nthroot (x,3) Be very careful though. If x is negative, it will return a complex number, because there are indeed THREE cube roots of a negative number. Two of them are complex. nthroot will give you the root you would expect however. Theme Copy (-2)^ (1/3) ans = 0.62996 + 1.0911i Web6 apr. 2024 · You probably have a uint8 input with values from 0-255. sqrt then does its thing and computes the square root for each element, and converts it to a double.
