RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Calculates the exponent of every array element.

The function cv::exp calculates the exponent of every element of the input array:

\texttt{dst} [I] = e^{ src(I) }

The maximum relative error is about 7e-6 for single-precision input and less than 1e-10 for double-precision input. Currently, the function converts denormalized values to zeros on output. Special values (NaN, Inf) are not handled.

exp(src: Mat, dst: Mat): void;

src

input array.

dst

Output destination, filled by the native operation. output array of the same size and type as src.
