zeros(1,8)意思就是一个一行8列的零矩阵。因为zeros(8)相当于是zeros(8,8)的简写形式,括号里面的数字,一个是表示多少行,一个是表示多少列。zeros功能是返回一个m×n×p×...的double类零矩阵的一个函数。在MATLAB中,此函数相关信息如下:二维用法:zeros(m,n)或zeros(n)功能:zeros(m,...
2 番目より後の次元のサイズが1の場合、それらの次元はzerosで無視されます。たとえば、zeros([3 1 1 1])は 3 行 1 列のゼロのベクトルを生成します。 例:sz = [2 3 4]は、2×3×4 の配列を作成します。 データ型:double|single|int8|int16|int32|int64|uint8|uint16|uint32|uint64...
第一种是Matrix Market (.mtx 格式),中间right hand side 是方程组 Ax=b 的右端项b。 第二种是 Harwell—Boeing 即(HB 格式) .rua 格式 。 注:mtx格式的矩阵就是通常的坐标存储方式,记录所有非零元的行和对应的列,而HB格式是新的存储方式,按照某种压缩原理,记录非零元,简单讲就是HB格式效率更高,同样...
