Matrix API Reference

Matrix library functions can be divided into three types:

• Value operations
• Vector operations
• Matrix operations

In addition, matrix library contains

• ConversionFrom functions
• ConversionTo functions
• Other functions

Value operations

Value operations work over individual values in a matrix, usually transforming them in some way.

# mat.mapValues( mapping function ): Matrix

Maps the values of the matrix to new values using a function

// The new matrix contains the squares of the elements from the original matrix
val squaredMatrix = matrix.mapValues{ value : Int => value * value }

# mat.filterValues( filter function ) : Matrix

Keep only the values of the matrix that set the function to true

// The new matrix contains only the positive non-zero elements from the matrix
val filteredMatrix = matrix.filterValues{ _ > 0 }

# mat.binarizeAs[NewValT] : Matrix

Sets all of the non-zero values of the matrix to the one element of the type

// The new matrix contains ones as integers for all non-zero values from the matri
val binMatrix = matrix.binarizeAs[Int]
