+# dsyr
+
+> Perform the symmetric rank 1 operation `A = α*x*x^T + A`.
+
+
+
+## Usage
+
+```javascript
+var dsyr = require( '@stdlib/blas/base/dsyr' );
+```
+
+#### dsyr( order, uplo, N, α, x, sx, A, LDA )
+
+Performs the symmetric rank 1 operation `A = α*x*x^T + A` where `α` is a scalar, `x` is an `N` element vector, and `A` is an `N` by `N` symmetric matrix.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 0.0, 1.0, 2.0, 0.0, 0.0, 1.0 ] );
+var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
+
+dsyr( 'row-major', 'upper', 3, 1.0, x, 1, A, 3 );
+// A => [ 2.0, 4.0, 6.0, 0.0, 5.0, 8.0, 0.0, 0.0, 10.0 ]
+```
+
+The function has the following parameters:
+
+- **order**: storage layout.
+- **uplo**: specifies whether the upper or lower triangular part of the symmetric matrix `A` should be referenced.
+- **N**: number of elements along each dimension of `A`.
+- **α**: scalar constant.
+- **x**: input [`Float64Array`][mdn-float64array].
+- **sx**: index increment for `x`.
+- **A**: input matrix stored in linear memory as a [`Float64Array`][mdn-float64array].
+- **lda**: stride of the first dimension of `A` (a.k.a., leading dimension of the matrix `A`).
+
+The stride parameters determine how elements in the input arrays are accessed at runtime. For example, to iterate over every other element of `x` in reverse order,
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 0.0, 1.0, 2.0, 0.0, 0.0, 1.0 ] );
+var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+
+dsyr( 'row-major', 'upper', 3, 1.0, x, -2, A, 3 );
+// A => [ 26.0, 17.0, 8.0, 0.0, 10.0, 5.0, 0.0, 0.0, 2.0 ]
+```
+
+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 arrays...
+var x0 = new Float64Array( [ 1.0, 1.0, 1.0, 1.0 ] );
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 0.0, 1.0, 2.0, 0.0, 0.0, 1.0 ] );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dsyr( 'row-major', 'upper', 3, 1.0, x1, -1, A, 3 );
+// A => [ 2.0, 3.0, 4.0, 0.0, 2.0, 3.0, 0.0, 0.0, 2.0 ]
+```
+
+#### dsyr.ndarray( uplo, N, α, x, sx, ox, A, sa1, sa2, oa )
+
+Performs the symmetric rank 1 operation `A = α*x*x^T + A`, using alternative indexing semantics and where `α` is a scalar, `x` is an `N` element vector, and `A` is an `N` by `N` symmetric matrix.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 0.0, 1.0, 2.0, 0.0, 0.0, 1.0 ] );
+var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
+
+dsyr.ndarray( 'upper', 3, 1.0, x, 1, 0, A, 3, 1, 0 );
+// A => [ 2.0, 4.0, 6.0, 0.0, 5.0, 8.0, 0.0, 0.0, 10.0 ]
+```
+
+The function has the following additional parameters:
+
+- **ox**: starting index for `x`.
+- **sa1**: stride of the first dimension of `A`.
+- **sa2**: stride of the second dimension of `A`.
+- **oa**: starting index for `A`.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example,
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var A = new Float64Array( [ 1.0, 2.0, 3.0, 0.0, 1.0, 2.0, 0.0, 0.0, 1.0 ] );
+var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
+
+dsyr.ndarray( 'upper', 3, 1.0, x, -2, 4, A, 3, 1, 0 );
+// A => [ 26.0, 17.0, 8.0, 0.0, 10.0, 5.0, 0.0, 0.0, 2.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- `dsyr()` corresponds to the [BLAS][blas] level 2 function [`dsyr`][blas-dsyr].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ones = require( '@stdlib/array/ones' );
+var dsyr = require( '@stdlib/blas/base/dsyr' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+
+var N = 3;
+
+var A = ones( N*N, opts.dtype );
+var x = discreteUniform( N, -10.0, 10.0, opts );
+
+dsyr( 'row-major', 'upper', 3, 1.0, x, 1, A, 3 );
+console.log( A );

+{{alias}}( order, uplo, N, α, x, sx, A, lda )
+ Performs the symmetric rank 1 operation `A = α*x*x^T + A` where `α` is a
