示例1: Mul
/// <summary>
/// Multiplies <paramref name="vector"/> by <paramref name="number"/>.
/// </summary>
/// <param name="vector">The vector.</param>
/// <param name="number">The number.</param>
/// <param name="parameters">An object that contains all parameters and functions for expressions.</param>
/// <returns>The product of matrices.</returns>
public static Vector Mul(this Vector vector, IExpression number, ExpressionParameters parameters)
{
var n = (double)number.Calculate(parameters);
#if NET40_OR_GREATER
var numbers = (from num in vector.Arguments.AsParallel().AsOrdered()
select new Number((double)num.Calculate(parameters) * n))
.ToArray();
#else
var numbers = (from num in vector.Arguments
select new Number((double)num.Calculate(parameters) * n))
.ToArray();
#endif

{
expression = parser.Parse(strExp);
if (!expression.ResultType.HasFlag(ExpressionResultType.Boolean))
throw new InvalidOperationException();
