/**
* Takes elements from one of two single-precision complex floating-point strided arrays depending on a condition.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {BooleanArray} condition - condition array
* @param {integer} strideC - stride length for `condition`
* @param {NonNegativeInteger} offsetC - starting index for `condition`
* @param {Complex64Array} x - first input array
* @param {integer} strideX - stride length for `x`
* @param {NonNegativeInteger} offsetX - starting index for `x`
* @param {Complex64Array} y - second input array
* @param {integer} strideY - stride length for `y`
* @param {NonNegativeInteger} offsetY - starting index for `y`
* @param {Complex64Array} out - output array
* @param {integer} strideOut - stride length for `out`
