Return the minimum accessible index based on a set of provided strided array parameters.
npm install @stdlib/strided-base-min-view-buffer-indexWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Return the minimum accessible index based on a set of provided strided array parameters.
``bash`
npm install @stdlib/strided-base-min-view-buffer-index
`javascript`
var minViewBufferIndex = require( '@stdlib/strided-base-min-view-buffer-index' );
#### minViewBufferIndex( N, stride, offset )
Returns the minimum accessible index based on a set of provided strided array parameters.
`javascript`
var idx = minViewBufferIndex( 3, -2, 10 );
// returns 6
- If N <= 0, the function returns the specified offset; however, do note that, when N equals zero, no strided array elements should be accessed.
`javascript
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' );
var minViewBufferIndex = require( '@stdlib/strided-base-min-view-buffer-index' );
// Generate a random number of indexed elements:
var N = discreteUniform( 10, 20 );
// Generate a random stride length:
var stride = discreteUniform( -10, 10 );
// Generate a random offset:
var offset = discreteUniform( 0, 100 ) + ( ( stride < 0 ) ? (1-N)*stride : 0 );
// Compute the minimum accessible index:
var idx = minViewBufferIndex( N, stride, offset );
console.log( 'N: %d, stride: %d, offset: %d => %d', N, stride, offset, idx );

#include "stdlib/strided/base/min_view_buffer_index.h"
#### stdlib_strided_min_view_buffer_index( N, stride, offset )
Returns the minimum accessible index based on a set of provided strided array parameters.
`c
#include "stdlib/strided/base/min_view_buffer_index.h"
#include
int64_t offset = stdlib_strided_min_view_buffer_index( 3, -2, 10 );
// returns 6
`
The function accepts the following arguments:
- N: [in] int64_t number of indexed elements.[in] int64_t
- stride: index increment.[in] int64_t
- offset: starting index.
`c`
int64_t stdlib_strided_min_view_buffer_index( const int64_t N, const int64_t stride, const int64_t offset );
`c
#include "stdlib/strided/base/min_view_buffer_index.h"
#include
#include
#include
int main( void ) {
// Specify the number of indexed elements:
int64_t N = 6;
// Define a stride:
int64_t stride = -2;
// Define an offset:
int64_t offset = 100;
// Compute the minimum accessible index:
int64_t idx = stdlib_strided_min_view_buffer_index( N, stride, offset );
// Print the results:
printf( "N: %"PRId64", stride: %"PRId64", offset: %"PRId64" => idx: %"PRId64"\n", N, stride, offset, idx );
}

- [@stdlib/strided-base/offset-view][@stdlib/strided/base/offset-view]: return a typed array view having the same data type as a provided input typed array and starting at a specified index offset.
