Method At

tensor/string.go:160–173

At is the gonum/mat.Matrix interface method for returning 2D matrix element at given row, column index. Assumes Row-major ordering and logs an error if NumDims < 2.

// T is the gonum/mat.Matrix transpose method.
// It performs an implicit transpose by returning the receiver inside a Transpose.
