MathNet Matrix MapIndexInplace confusion about arguments -


MapIndexInplace is documented to take a funk (int, int, float, float). I do not know what the second float value is. Can anyone explain?

funk & lt; Int, int, float, float & gt; Representative represents a function in which two floats and a float in the form of logic and return value in the form of a float. So the second float indicates the return value of the function.

Map IndekInstes will provide this type of sign (or optionally each non-zero) matrix element with three arguments for each (index, index j, current value V) and replace the matrix element value with the value returned by the function.
