Legacy Name: cumtrapz


Computes the cumulative trapezoidal integrals of a vector or matrix.



Name Description
a Specifies a vector or matrix.
b Specifies whether to compute the column-wise or the row-wise cumulative trapezoidal integrals of a. b is an integer that accepts the following values.

1 (default) Computes the column-wise cumulative trapezoidal integrals.
2 Computes the row-wise cumulative trapezoidal integrals.


Name Description
c Returns the cumulative trapezoidal integrals of a. If a is a vector, c returns a vector of the cumulative trapezoidal integrals of a. If a is a matrix and you do not specify b, c returns a matrix whose elements are the column-wise cumulative trapezoidal integrals of a. c is a vector or matrix of the same size as a.
