Functions
Name
Brief
Example
ocmath_2d_integrate
To compute the volume beneath the surface defined by the matrix, starting from zero-level.
Examples
ocmath_function_integral
Perform integral on specified function in the given data range. It can be used for improper integral like infinite integral.
Examples
ocmath_integrate
Integrate area under curve using Trapezoid Rule. Missing values are ignored.
Examples
ocmath_numeric_integral
This function performs incomplete integral from pxData[0] to x. If x is found in pxData, the function calls ocmath_integrate; otherwise linear interpolation is used to find integral result.
