Returns the number of elements in each dimension of array.
The connector pane displays the default data types for this polymorphic function.

Inputs/Outputs
array
—
array can be an n-dimensional array of any type.
size(s)
—
size(s) is a 32-bit integer if array is one-dimensional (1D). If array is multidimensional, the returned value is a 1D array in which each element is a 32-bit integer that represents the number of elements in the corresponding dimension of array. The order of elements in the return array corresponds to row-major order. Thus, vol is the first index, followed by page, row, and column. These names are index identifiers and have no other meaning. |
FPGA Module Details
The following details apply when you use this object in an FPGA VI.
Note The following details are subject to change with each version of the LabVIEW FPGA Module.
| Single-Cycle Timed Loop | Supported. |
| Usage | N/A |
| Timing | This function requires no clock cycles to execute because it does not include an internal register. |
| Resources | This function consumes no FPGA resources because it is purely a wiring operation. |
