Exact sensitivity analysis for the Ishigami function
exact = nisp_ishigamisa ( a , b )
a 1-by-1 matrix of doubles, the first parameter.
a 1-by-1 matrix of doubles, the second parameter.
a struct with the following fields: expectation, var, S1, S2, S3, S12, S13, S23, S123, ST1, ST2, ST3.
This function returns exact sensitivity indices of the Ishigami function.
a=7.; b=0.1; exact = nisp_ishigamisa ( a , b )
