MATLAB provides themax()function used to find the maximum value in an array or matrix. It has different modes for processing data and can be helpful in finding the maximum value in a variety of scenarios. In this tutorial, we have learned the usage of themax()function with examples. By ...
y=max(x) %求向量x中的最大值 [y,l]=max(x) %求向量x中的最大值及其该元素的位置 1.2 求矩阵的最大值和最小值 求矩阵A的最大值的函数有3种调用格式,分别是: (1) max(A):返回一个行向量,向量的第i个元素是矩阵A的第i列上的最大值。 (2) [Y,U]=max(A):返回行向量Y和U,Y向量记录A的...

Sparse matrices have a different storage convention from full matrices in MATLAB. The parameterpais still an array of double-precision numbers or logical values, but this array contains only nonzero data elements. There are three additional parameters:nzmax,ir, andjc. Use themwSizeandmwIndextypes...
