fMin(, fMax(
fMin( (function minimum) and fMax( (function maximum) return the value at which the local
minimum or local maximum value of
expression with respect to variable occurs, between lower and
upper values for variable. fMin( and fMax( are not valid in expression. The accuracy is controlled by
tolerance (if not specified, the default is 1âL5).
fMin(expression,variable,lower,upper[,tolerance])
fMax(expression,variable,lower,upper
[,tolerance])
Note: In this guidebook, optional arguments and the commas that accompany them are enclosed
in brackets ([
