Could someone explain below part of code please ? I do not understand the first part [~,b]

 [~,b] = min(abs(RealEL1));

Answer 1

[Matt J]

These are the outputs of the min() function. b is the location of the minimum value. ~ means that the first output argument, the minimum value itself, is not to be assigned to any variable.

Answer 2

The ~ ignores the first output of min as you're only interested in the index of the minimum, not its actual value.
