Detailed Description

Returns the size and number of dimensions of the array objects.

These functions return the size and number of the dimensions of the array object.

Function Documentation

dim4 dims ( ) const

Return a dim4 object with the dimensions of the array.

array a(4,5,6);
//create array of the same size
array b(a.dims());

Examples:: examples/financial/black_scholes_options.cpp, examples/image_processing/optical_flow.cpp, examples/machine_learning/kmeans.cpp, and examples/machine_learning/neuralnetwork.cpp.

int dims ( unsigned dim ) const

Return the size of the dimension specified by index dim (zero-indexed).

array a(4,5);

printf("%d,%d\n",a.dims(0),a.dims(1)); // 4,5

Parameters

[in] dim The dimension to query

int numdims ( ) const

Returns the number of dimensions whose size is greater then one.

array a = constant(0,4,5,6);
cout << a.dims().numdims() << endl;
//Returns 3
