## reshapearray

reshapearray — Reshape an array, maintaining its capacity

## Description

Plugin opcode in emugens.

The reshapearray opcode changes the shape of an array, as long as this does not modify its capacity. It can be used to convert a 1D to a 2D array, or viceversa, or simply to modify the size of its dimensions, as long as the product remains constant.

## Syntax

    reshapearray array[], isize0 [, isize1 ]

## Initialization

array[] - The array to be reshaped (this is done inplace)

isize0 - The size of the first dimension

isize1 - The size of the second dimension (0 for 1D arrays). Defaults to 0

## Examples

Here is an example of the reshapearray opcode. It uses the file reshapearray.csd.

    reshapearray

      Reshape an array, maintaining the capacity of the array
      (it does NOT resize the array).

      You can reshape a 2D array to another array of equal capacity
      of reshape a 1D array to a 2D array, or a 2D array to a 1D
      array

      reshapearray array[], inumrows, inumcols=0

      works with i and k arrays, at i-time and k-time
