2D Volume Integration tool calculates the volume between the plane Z=0 and the matrix surface, by two-dimensional integration. Two-dimensional volume integration can be performed on a matrix window or on a plot of matrix data.
The operating matrix.
Trim missing values if this parameter is true.
This function computes the volume beneath the matrix surface using a numeric integral method.
For a continuous surface , the volume beneath it can be computed as:
Using a numeric method, it can be written as:
where the M, N is the number of the rows and columns of the matrix respectively. In the actual process of computing,
is used instead of .
