Hello Matlab Users, I have a A matrix: A=[2 4;2 10;2 15;5 14;6 7;6 15;8 16;8 10] and I want to see the first row where I meet let's say "6"(which is the 5th row).Could you help me in solving that problem,please?

在使用MATLAB时，[m n]=find(a==max)命令用于查找矩阵a中等于max的元素的位置。首先需要确保矩阵a存在。例如：>>a = rand(1,10);这行代码创建了一个1x10的随机数矩阵a。接下来可以使用max函数获取矩阵中的最大值：>>b = max(a);这行代码将矩阵a中的最大值赋给变量b。然后使用find函数查...
Y is a matrix that has the same number of rows as there are dimensions in the problem. The matrix W = H*Y, although H is not formed explicitly. fmincon uses Hinfo to compute the preconditioner. For information on how to supply values for any additional parameters hmfun needs, see Passin...
Open in MATLAB Online I have a large matrix with with multiple rows and a limited (but larger than 1) number of columns containing values between 0 and 9 and would like to find an efficient way to identify unique row-wise combinations and their indices to then build sums (some...
Find number of zeros in a part of a matrixI need to find the number of zeros that are contained in a part of a matrix. For example if the matrix is [1 2 2 2 2 2 0 2 2 2 0 3 0 0 4 5 6 7 0 0 8] is there a fast way to get the number of zeros between the fifth ...
MATLAB Online で開く I am trying to make a function which is to find a certain number, or numbers above a threshold number, in a given matrix of unknown size. Preferably without any other function then if,else,while,for. functionsearch = searchMatrix(matrix) ...
But for a Matrix it is harder ThemeCopy R = [0 4 5 0 8 12 0 6] ; I want it to return ThemeCopy [2 3 1 2 4] I tried it like this (here size(Gates_used,1) is equal to the number of rows ) ThemeCopy forl = 1:size(Gates_used,1) ; ...
