This function rounds inputs to multiples of a fraction. For example, to round values in an array x to the nearest fifth, use roundfrac(x,1/5). Syntax Xrounded = roundfrac(X,fraction) Xrounded = roundfrac(X,fraction,option) Description Xrounded = roundfrac(X,fraction) rounds X to ...

This is a collection of MATLAB utilities developed by Kendrick Kay (kendrick@post.harvard.edu,http://kendrickkay.net). The philosophy of the code is to maximize power (i.e. the ability to perform many different things) and generality (i.e. the ability to re-use code for many different ...
