Matlab
Matlab是一个交互式的系统，它的基本运算单元是不需指定维数的矩阵，按照IEEE的数值计算标准（能正确处理无穷数Inf(Infinity)、无定义数NaN(not-a-number)及其运算）进行计算．(Matlab is an interactive system, its basic operation unit which is not specified dimension of the matrix, in accordance with the numerical calculation of IEEE standards (to correctly handle the infinite number of Inf (Infinity), no defined number of NaN (not-a-number) its operation) is calculated.)
