this(double[] vec, ulong row, ulong col, bool by_row);

this(double val, ulong row, ulong col, bool by_row);

void toString(void delegate(const(char)[]) sink);

Matrix change_shape();

string spread();

double opIndex(ulong i, ulong j);

void opIndexAssign(double value, ulong i, ulong j);

Matrix opUnary();

Matrix opBinary(double rhs);

Matrix opBinaryRight(double lhs);

Matrix opBinary(Matrix rhs);

Matrix transpose();

double[] cols(ulong idx);

double[] rows(ulong idx);

}

Constructors

this this(double[] vec, ulong row, ulong col, bool by_row): Default Constructor
this this(double val, ulong row, ulong col, bool by_row): Initialize with single number

Members

Functions

change_shape Matrix change_shape(): Change shape
cols double[] cols(ulong idx): Extract column - TODO: slice op
opBinary Matrix opBinary(double rhs): Binary ops with single number
opBinary Matrix opBinary(Matrix rhs): Binary ops with matrix
opBinaryRight Matrix opBinaryRight(double lhs): Binary ops with single number - right hand side
opIndex double opIndex(ulong i, ulong j): Getter
opIndexAssign void opIndexAssign(double value, ulong i, ulong j): Setter
opUnary Matrix opUnary(): Unary ops - negative
rows double[] rows(ulong idx): Extract rows - TODO: slice op
spread string spread(): Spread 1D to 2D
toString void toString(void delegate(const(char)[]) sink): Undocumented in source. Be warned that the author may not have intended to support it.
transpose Matrix transpose(): Transpose

Variables

by_row bool by_row;: Shape
col ulong col;: Column
