+{{alias}}( N, x, strideX )
     Computes the range of a strided array.
 
-
     The `N` and stride parameters determine which elements in the strided 
     array are accessed at runtime.
 
-
     Indexing is relative to the first index. To introduce an offset, use a 
     typed array view.
 
-
     If `N <= 0`, the function returns `NaN`.
 
-
     Parameters
     ----------
-
-
     N: integer
         Number of indexed elements.
 
-
     x: Array<number>|TypedArray
         Input array.
 
-
     strideX: integer
         Stride length.
 
-
     Returns
     -------
-
-
     out: number
         Range.
 
-
     Examples
     --------
-
-
     // Standard Usage:
     > var x = [ 1.0, -2.0, 2.0 ];
     > {{alias}}( x.length, x, 1 )
     4.0
 
-
     // Using `N` and stride parameters:
     > x = [ -2.0, 1.0, 1.0, -5.0, 2.0, -1.0 ];
     > var stride = 2;
     > {{alias}}( 3, x, stride )
     4.0
 
-
     // Using view offsets:
-    > var x0 = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, 3.0, 2.0, 5.0, -1.0 ] );
-    > var x1 = new {{alias:@stdlib/array/float64}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
+    > var x0 = new {{alias:@stdlib/array/float64}}
+    ( [ 1.0, -2.0, 3.0, 2.0, 5.0, -1.0 ] );
+    > var x1 = new {{alias:@stdlib/array/float64}}
+    ( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
     > stride = 2;
     > {{alias}}( 3, x1, stride )
     4.0
 
-
 {{alias}}.ndarray( N, x, strideX, offsetX )
-
-
     Computes the range of a strided array using alternative indexing 
     semantics.
 
-
     While typed array views mandate a view offset based on the underlying
     buffer, the `offset` parameter supports indexing semantics based on a
     starting index.
 
-
     Parameters
     ----------
-
-
     N: integer
         Number of indexed elements.
 
-
     x: Array<number>|TypedArray
         Input array.
 
-
     strideX: integer
         Stride length.
 
-
     offsetX: integer
         Starting index.
 
-
     Returns
     -------
-
-
     out: number
         Range.
 
-
     Examples
     --------
-
-
     // Standard Usage:
     > var x = [ 1.0, -2.0, 2.0 ];
     > {{alias}}.ndarray( x.length, x, 1, 0 )
     4.0
 
-
     // Using offset parameter:
     > var x = [ 1.0, -2.0, 3.0, 2.0, 5.0, -1.0 ];
     > {{alias}}.ndarray( 3, x, 2, 1 )
