Slice an array
Slices one dimension from an array by taking one element from the first dimension.
sliceArray(x,slice)
x |
An array |
slice |
The index of the slice to take from the first dimension of the array. |
sliceArray builds an extractor string containing the value of slice as the first element and as many commas as needed to match the dimensions of the array. It then applies the extractor function to x and returns the result. Note how the array "slice" swaps dimensions in the example.
The desired slice of the array.
