and I need max and its index of each row; which I type [MAC col]=max(A,[],2); the results it gives me is MAC=[0.57 1.00 0.10] and col=[2 3 2]. What I need is to have col=[2 3 4] and MAC=[0.57 1.00 0.09] which ha
M = max(A) returns the maximum elements of an array. If A is a vector, then max(A) returns the maximum of A. If A is a matrix, then max(A) is a row vector containing the maximum value of each column of A. If A is a multidimensional array, then max(A) operates along the ...
是“Matrix Laboratory”的缩写,意为“矩阵实验室”,是当今美国很流行的科学计算软件.信息技术、计算机技术发展到今天,科学计算在各个领域得到了广泛的应用.在许多诸如控制论、时间序列分析、系统仿真、图像信号处理等方面产生了大量的矩阵及其相应的计算问题.自己去编写大量的繁复的计算程序,不仅会消耗大量的时间和精力,...
The rank of a matrix A is computed as the number of singular values that are larger than a tolerance. By default, the tolerance is max(size(A))*eps(norm(A)). However, you can specify a different tolerance with the command rank(A,tol). ...

事实上,执行加法运算时,MATLAB会将大小兼容的矩阵隐式扩展为相同的大小,然后再将对应位置的元素相加,这种计算方式在MATLAB中称为“按对应位置的元素运算”。我们在上一节介绍的min函数和max函数在计算两个矩阵对应位置元素的最小值和最大值时也支持上表五种模式。
