Public Shared Function min ( A As BaseArray(Of Double), Optional I As OutArray(Of Long) = Nothing, Optional dim As Integer = -1, Optional keepdim As Boolean = true ) As RetArray(Of Double) Dim A As BaseArray(Of Double) Dim I As OutArray(Of Long) Dim dim As Integer Dim keepdim As Boolean Dim returnValue As RetArray(Of Double) returnValue = numpy.min(A, I, dim, keepdim)
- Type: ILNumericsBaseArray
- I (Optional)
- Type: ILNumericsOutArray
[Optional] Output: 0-based index values of the found elements along the working dimension. Default: (null) don't return the indices.
- dim (Optional)
The index of the dimension to be reduced.
- keepdim (Optional)
[Optional] True: reduced singleton dimension is not removed from the output (default). False: the new singleton dimension is removed.
Return ValueType: RetArray
New array with the same shape as A except that the dimension specified by dim is reduced to length min(1,A.S[dim]) and removed if keepdim is false.
|If A.S[dim] == 0 and keepdim was false.|
Empty arrays are handled in the same way as other shapes: the dimension specified by dim is reduced to 1. If A.S[dim] == 0 the dims dimension length in the array returned will also be 0.
Scalar arrays: numpy scalars give a numpy scalar (0 dim) as output.
Special floating point values (for floating point element types): positive and negative infinity are handled in the regular way. NaN ('not a number') values are ignored. If all elements in a working dimension are NaN, NaN is returned as result in the corresponding output element.
If the optional output parameter I is not null on entry the function computes and returns the indices in A of the values returned. Thus, I has the same shape as the return array. If the storage of I on entry is sufficient (i.e.: large enough and not shared with other arrays) it will be directly used for storing the indices and I is reshaped as required. Otherwise, a new array is created and returned. In order to safe the index computation null can be provided as I which is the default.
If I is requested and multiple elements along the working dimension in A have the same minimum value it is undefined which element is 'picked' for the output. Hence, in this case the corresponding value in I is undefined and may point to the first or any other occurrence of the value returned from the working dimension.
