Method Details

ensureIdentity

public static DMatrixRMaj ensureIdentity(@Nullable
 @Nullable DMatrixRMaj A,
 int numRows,
 int numCols)

ensureZeros

public static DMatrixRMaj ensureZeros(@Nullable
 @Nullable DMatrixRMaj A,
 int numRows,
 int numCols)

checkZerosLT

public static DMatrixRMaj checkZerosLT(@Nullable
 @Nullable DMatrixRMaj A,
 int numRows,
 int numCols)

Creates a zeros matrix only if A does not already exist. If it does exist it will fill the lower triangular portion with zeros.

checkZerosUT

public static DMatrixRMaj checkZerosUT(@Nullable
 @Nullable DMatrixRMaj A,
 int numRows,
 int numCols)

Creates a zeros matrix only if A does not already exist. If it does exist it will fill the upper triangular portion with zeros.
