Logical mxAlgebra() operators
omxNot computes the unary negation of the values of a matrix.
omxAnd computes the binary and of two matrices.
omxOr computes the binary or of two matrices.
omxGreaterThan computes a binary greater than of two matrices.
omxLessThan computes the binary less than of two matrices.
omxApproxEquals computes a binary equals within a specified epsilon of two matrices.
omxNot(x) omxAnd(x, y) omxOr(x, y) omxGreaterThan(x, y) omxLessThan(x, y) omxApproxEquals(x, y, epsilon)
x |
the first argument, the matrix which the logical operation will be applied to. |
y |
the second argument, applicable to binary functions. |
epsilon |
the third argument, specifies the error threshold for omxApproxEquals. Abs(x[i][j]-y[i][j]) must be less than epsilon[i][j]. |
