s-function within s-function
This question might not make sense, I am still a beginner. Is it possible to call an s-function from inside another s-function. Say when calculating my output I want to call one s-function in my input is something and another if the input is something else.

OLS problem with non-linear constraint
Hi all, I am trying to fit a "replicating portfolio" to a given structure of cash-flows. The cash flows are in stochastic form, i.e. a set of "scenarios" with a cash flow to match for each scenario. For this, I want to solve a linear least squares problem in the form of min (y - Xb), where y(i) is my cash ... 28 Apr 2010 14:00
