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 ...

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。
For example, islocalmax(A,2) finds local maximum of each row of a matrix A. example TF = islocalmax(___,Name,Value) specifies parameters in addition to any of the input argument combinations in previous syntaxes for finding local maxima using one or more name-value arguments. For ...
If eigs fails to converge for a given matrix, increase the number of Lanczos basis vectors by increasing the value of 'SubspaceDimension'. As secondary options, adjusting the maximum number of iterations, 'MaxIterations', and the convergence tolerance, 'Tolerance', also can help with convergence...
