PnetMatrix class

matrix of type int, can be constructed by calling PnetMatrix() or PnetMatrix.from()

Implemented types

Constructors

PnetMatrix(List<List<int>> values)
creates a matrix by passing a 2d list of values
PnetMatrix.empty(int x, int y)
creates a new empty matrix given it's x width and y height
PnetMatrix.from(PnetMatrix matrix)
creates a new matrix as a copy from another matrix

Methods

add(PnetMatrix matrix) → void
add matrix to another matrix both must be of the same size
copy(PnetMatrix matrix) → void
copy values from a matrix to this one
get(int x, int y) → int
get value at position x and y
ifEqual(PnetMatrix matrix) → bool
compares if matrix is equal to matrix in a corresponding element by element manner
logicalAnd(PnetMatrix matrix) → void
logical and matrix to another matrix, element by element both must have the same size
logicalNot() → void
logical negate the matrix, truthy values becomes 0 and falsy values becomes 1
multiply(PnetMatrix matrix) → void
multiply matrix by another matrix
multiplyElementByElement(PnetMatrix matrix) → void
multiply by another matrix, element by element instead of normal matrix multiplication both must have the same size
multiplyScalar(int scalar) → void
multiply matrix by a scalar
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
set(int x, int y, int value) → void
set value at position x and y
setAll(int value) → void
sets all values of a matrix to the specified value
toString() → String
A string representation of this object.
inherited
transpose() → void
transpose the matrix

Operators

operator ==(Object other) → bool
The equality operator.
