# chgcoltype

Purpose
Used to change the type of a specified set of columns in the matrix.
Synopsis
`chgcoltype(prob, colind, coltype, ncols = x_max_vec_length(colind, coltype))`
Arguments

prob | The current problem.
colind | Integer array of length ncols containing the indices of the columns.
coltype | Character array of length ncols giving the new column types: C indicates a continuous column; B indicates a binary column; I indicates an integer column. S indicates a semicontinuous column. The semicontinuous lower bound will be set to 1.0. R indicates a semiinteger column. The semiinteger lower bound will be set to 1.0. P indicates a partial integer column. The partial integer limit will be set to 1.0.
ncols | Number of columns to change.
