Public Attributes

bool bDeleteArrays
 bDeleteArrays is true if we delete the arrays in garbage collection set to true by default
int startSize
 startSize is the dimension of the starts array -- should equal number of rows + 1
int valueSize
 valueSize is the dimension of the values array
int * starts
 starts holds an integer array of start elements, each start element pints to the start of partials for that row
int * conVals
 conVals holds an integer array of integers, conVals[i] is the number of constant terms in the gradient for row i.
int * indexes
 indexes holds an integer array of variable indicies.
