+# resolve
+
+> Return the matrix triangle string associated with a supported BLAS matrix triangle value.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var resolve = require( '@stdlib/blas/base/matrix-triangle-resolve-str' );
+```
+
+#### resolve( value )
+
+Returns the matrix triangle string associated with a BLAS matrix triangle value.
+
+```javascript
+var str2enum = require( '@stdlib/blas/base/matrix-triangle-str2enum' );
+
+var v = resolve( 'upper' );
+// returns 'upper'
+
+v = resolve( str2enum( 'upper' ) );
+// returns 'upper'
+```
+
+If unable to resolve a matrix triangle string, the function returns `null`.
+
+```javascript
+var v = resolve( 'beep' );
+// returns null
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var str2enum = require( '@stdlib/blas/base/matrix-triangle-str2enum' );
+var resolve = require( '@stdlib/blas/base/matrix-triangle-resolve-str' );
+
+var v = resolve( str2enum( 'upper' ) );
+// returns 'upper'
+
+v = resolve( str2enum( 'lower' ) );
+// returns 'lower'
