Public Methods

Documentation

A matrix class for double precision floating point numbers. EST_DMatrix x should be used instead of double **x wherever possible.

EST_DMatrix(int m, int n)

size constructor

EST_DMatrix(const EST_DMatrix &a)

copy constructor

EST_DMatrix(const EST_DMatrix &a, int b)

CHECK - what does this do???

EST_DMatrix()

default constructor

EST_write_status save(const EST_String &filename, const EST_String &type = EST_DMatrix::default_file_type)

Save in file (ascii or binary)

EST_read_status load(const EST_String &filename)

Load from file (ascii or binary as defined in file)

EST_write_status est_save(const EST_String &filename, const EST_String &type)

Save in file in est format

EST_read_status est_load(const EST_String &filename)

Load from file in est format (binary/ascii defined in file itself)

void copyin(double** x, int rows, int cols)

Copy 2-d array x of size rows x cols into matrix

EST_DMatrix& operator+=(const EST_DMatrix &a)

Add elements of 2 same sized matrices

EST_DMatrix& operator-=(const EST_DMatrix &a)

Subtract elements of 2 same sized matrices

EST_DMatrix& operator*=(const double f)

elementwise multiply by scalar

EST_DMatrix& operator/=(const double f)

elementwise divide by scalar

This class has no child classes.
