Consider an m-by-n input matrix, A: min(A,[],1) computes the minimum of the elements in each column of A and returns a 1-by-n row vector. min(A,[],2) computes the minimum of the elements in each row of A and returns an m-by-1 column vector. vecdim— Vector of dimensions...
min : 求最小值(minimum value) min函数主要有两种用法: 用法一:求两个矩阵对应位置元素的最小值: min(A,B)。 矩阵A和矩阵B的大小可以不一样,只要保证矩阵A和矩阵B具有兼容的大小就能够计算,MATLAB矩阵运算中支持的兼容模式会在“3.1.2算术运算”这一小节中详细介绍。 下面再举两个例子:表中第三列是运行...
and returns the R-by-2 matrix pr of minimum and maximum values for each row of P. Alternatively, P can be an M-by-N cell array of matrices. Each matrix P{i,j} should have Ri rows and Q columns. In this case, minmax returns an M-by-1 cell array where the mth element is an...
