+# igamax
+
+> Find the index of the first element having maximum absolute value.
+
+
+
+## Usage
+
+```javascript
+var igamax = require( '@stdlib/blas/base/igamax' );
+```
+
+#### igamax( N, x, strideX )
+
+Finds the index of the first element having maximum absolute value.
+
+```javascript
+var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+
+var idx = igamax( x.length, x, 1 );
+// returns 3.0
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **x**: first input [`Array`][mdn-array] or [`typed array`][mdn-typed-array].
+- **strideX**: index increment for `x`.
+
+The `N` and `strideX` parameters determine which elements in `x` are accessed at runtime. For example, to find index of element having maximum absolute value traversing every other value,
+
+```javascript
+var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+
+var idx = igamax( 4, x, 2 );
+// returns 2
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+// Initial array:
+var x0 = new Float64Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] );
+
+// Create offset view:
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Find index of element having maximum absolute value for every other element...
+var idx = igamax( 3, x1, 2 );
+// returns 2
+```
+
+If either `N` is less than `1` or `strideX` is less than or equal to `0`, the function returns `0`.
+
+#### igamax.ndarray( N, x, strideX, offsetX )
+
+Finds the index of the first element having maximum absolute value using alternative indexing semantics.
+
+```javascript
+var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+
+var idx = igamax.ndarray( x.length, x, 1, 0 );
+// returns 3
+```
+
+The function has the following additional parameter:
+
+- **offsetX**: starting index for `x`.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the `offset` parameter supports indexing semantics based on a starting index. For example, to find the index of the element having the maximum absolute value starting from second index,
+
+```javascript
+var x = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];
+
+var idx = igamax.ndarray( 5, x, 1, 1 );
+// returns 4
+```
+
+
+
+
+
+
+
+## Notes
+
+- If `N < 1` or `strideX <= 0`, both functions return `0`.
+- `igamax()` corresponds to the [BLAS][blas] level 1 function [`idamax`][idamax] with the exception that this implementation works with any array type, not just Float64Arrays. Depending on the environment, the typed versions ([`idamax`][@stdlib/blas/base/idamax], [`isamax`][@stdlib/blas/base/isamax], etc.) are likely to be significantly more performant.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var igamax = require( '@stdlib/blas/base/igamax' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+var x = discreteUniform( 10, 0, 500, opts );
+console.log( x );
+
+var idx = igamax.ndarray( x.length, x, 1, 0 );
+console.log( idx );
+```

+{{alias}}( N, x, strideX )
+ Finds the index of the first element having maximum absolute value.
+
+ The `N` and `strideX` parameters determine which elements in `x` are
+ accessed at runtime.
+
+ Indexing is relative to the first index. To introduce an offset, use typed
+ array views.
+
+ If `N < 1` or `strideX <= 0`, the function returns `0`.
+
+ Parameters
+ ----------
+ N: integer

+
+ x: Array|TypedArray
+ First input array.
+
+ strideX: integer
+ Index increment for `x`.
+
+ Returns
+ -------
+ idx: integer

+
+ Examples
+ --------
+ // Standard usage:
+ > var x = [ 4.0, 2.0, -3.0, 5.0, -1.0 ];
+ > var idx = {{alias}}( x.length, x, 1 )
+ 3

+ // Strides:

+{{alias}}.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
