Applies a modified Givens plane rotation.

@param {PositiveInteger} N - number of indexed elements
@param {Float32Array} x - first input array
@param {integer} strideX - `x` stride length
@param {Float32Array} y - second input array
@param {integer} strideY - `y` stride length
@param {Float32Array} param - parameters for the modified Givens transformation
@returns {Float32Array} `y`

@example
var Float32Array = require( '@stdlib/array/float32' );

var x = new Float32Array( [ 0.6, 0.1, -0.5, 0.8, 0.9, -0.3, -0.4 ] );
var y = new Float32Array( [ 0.5, -0.9, 0.3, 0.7, -0.6, 0.2, 0.8 ] );
var param = new Float32Array( [ 0.0, 0.0, 2.0, -3.0, 0.0 ] );

srotm( 4, x, -1, y, -2, param );
// x => <Float32Array>[ ~-0.9, ~-0.8, ~1.3, ~-1.6, ~0.9, ~-0.3, ~-0.4 ]
// y => <Float32Array>[ ~1.7, ~-0.9, ~0.5, ~0.7, ~-1.6, ~0.2, ~2.4 ]
