Incomplete gamma function in matlab
WebThe MATLAB ® gammainc function uses the definition of the lower incomplete gamma function, gammainc (z, nu) = 1 - igamma (nu, z)/gamma (nu) . The order of input arguments differs between these functions. Examples Compute Incomplete Gamma Function for Numeric and Symbolic Arguments WebSep 11, 2024 · Regardless, It looks like gammainc does not accepts complex arguments. As well, the symbolic toolbox does not have an incomplete gamma.
