+# cosineWave
+
+> Generate a cosine wave in a strided array.
+
+
+
+
+
+A cosine waveform is represented by the following equation
+
+
+
+```math
+f(t; \tau, a, \varphi) = a \cdot \cos \frac{2\pi(t-\varphi)}{\tau}
+```
+
+
+
+
+
+where `τ` is the period, `a` is the peak amplitude, and `φ` is the phase offset.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var cosineWave = require( '@stdlib/simulate/strided/cosine-wave' );
+```
+
+#### cosineWave( N, period, amplitude, phaseOffset, x, strideX )
+
+Generates a cosine wave in a strided array.
+
+```javascript
+var x = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];
+
+cosineWave( x.length, 4, 1.0, 0, x, 1 );
+// x => [ 1.0, 0.0, -1.0, 0.0, 1.0, 0.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **period**: period (i.e., the number of elements before a cosine wave repeats).
+- **amplitude**: peak amplitude.
+- **phaseOffset**: phase offset (in units of elements; zero-based). A negative offset translates a waveform to the left. A positive offset translates a waveform to the right.
+- **x**: input [`Array`][mdn-array] or [`typed array`][mdn-typed-array].
+- **strideX**: stride length.
+
+The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to generate a cosine wave in every other element:
+
+```javascript
+var x = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];
+
+cosineWave( 3, 4, 1.0, 0, x, 2 );
+// x => [ 1.0, -2.0, 0.0, -4.0, -1.0, -6.0 ]
+```
+
+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 an offset view...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Generate a cosine wave in every other element...
+cosineWave( x1.length, 4, 1.0, 0, x1, 2 );
+// x0 => [ 1.0, 1.0, 3.0, 0.0, 5.0, -1.0 ]
+```
+
+#### cosineWave.ndarray( N, period, amplitude, phaseOffset, x, strideX, offsetX )
+
+Generates a cosine wave in a strided array using alternative indexing semantics.
+
+```javascript
+var x = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];
+
+cosineWave.ndarray( x.length, 4, 1.0, 0, x, 1, 0 );
+// x => [ 1.0, 0.0, -1.0, 0.0, 1.0, 0.0 ]
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index.
+
+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 access only the last three elements:
+
+```javascript
+var x = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];
+
+cosineWave.ndarray( 3, 4, 1.0, 0, x, 1, x.length-3 );
+// x => [ 1.0, -2.0, 3.0, 1.0, 0.0, -1.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- If `N <= 0`, both functions return `x` unchanged.
+- Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]).
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var cosineWave = require( '@stdlib/simulate/strided/cosine-wave' );
+
+var x = discreteUniform( 10, -100, 100, {
+ 'dtype': 'float64'
+});
+console.log( x );
+
+cosineWave( x.length, 4, 1.0, 0, x, 1 );
+console.log( x );
+```
