matMaxs: Row or Column Maximum Values of a Matrix

In lsei: Solving Least Squares or Quadratic Programming Problems under Equality/Inequality Constraints

Description

Finds either row or column maximum values of a matrix.

Usage

matMaxs(x, dim = 1)

Arguments

x	numeric matrix.
dim	=1, for row maximum values; =2, for column maximum values.

Details

Matrix x may contain Inf or -Inf, but not NA or NaN.

Value

Returns a numeric vector with row or column maximum values.

The function is very much the same as using apply(x, 1, max) or apply(x, 2, max), but faster.
