# Max

Finds the maximum value of the elements of a matrix or a tensor.

## Inputs

input
A matrix or a tensor.
dimension
Specifies the dimension along which the maximum will be searched. -1 means maximum of all elements. For matrices, dimension 0 is rows (output will be 1-by-N) and 1 is columns (output will be N-by-1). For tensors, the specified dimension will be collapsed. For example, if the input is a 1×2×3×4 tensor and dimension is 1, the output will be a 1×3×4 tensor. If the size of the specified dimension is one, maximum is equal to reshaping the tensor. If dimension is greater or equal to the number of dimensions in the input tensor or matrix, the output will be an empty tensor or matrix.

## Outputs

output
A matrix or a tensor of the same type as the input. If dimension is -1, the output will be a scalar value.
