Now, there is reason why I don't want to use a max() or similar built-in function to find the maximum value of a matrix. My question is following: Imagine, we have a matrix, let's call it 'gauss' and looks like
How do you define a local maximum? I do not see how 21 and 24 are local maxima of the second column ... Stephen232016년 2월 22일 Closed as a duplicate (the other has an answer): http://www.mathworks.com/matlabcentral/answers/269366-find-local-max-in-a-matrix ...
I have matrix A with n rows and 2 columns. I would like to find rows which has the maximum and/or minimum of X and/or Y. Then, replace zero in these rows. For instance: I have matrix A and I would like to produce matrix B. ThemeCopy A= [0.1 0.5 0.3 0.9 0.4 0.8 0.4 0.2...
Hello everyone, Suppose there can be the max value at more than one location, how can I catch the first max value. ThemeCopy A = [6;7;21;4;9;21;5;1]; max(A(:)) [maxValue, linearIndexesOfMaxes] = max(A(:)); [rowsOfMaxes colsOfMaxes] = find(A == maxValue) a...
The 'find' command only returns the indices of all the non-zero elements of a matrix. I would like to know how to find the indices of just the maximum (or minimum) value. Sign in to answer this question.Accepted Answer MathWorks Support Team on 26 Nov 2024 Vot...

Find the maximum number and its location in the matrixIs this homework? If so, tag it as homework.Really really easy, and pretty much the same algorithm any any programming language, like others that you may know. Hint:編
通过find函数不仅可以找到满足条件的索引数,还可以找到其元素值,如: >> x(find(x<5,2)) ans = 3 4(五)max函数、min函数 max与min函数用法一致。 max:Largest elements in array,寻找最大值。 max(a) :寻找数组a中的最大元素。 max(a,b):返回a和b中的最大值,分一下情况: ...
x, lb, and ub can be passed as vectors or matrices; see Matrix Arguments. x = fmincon(fun,x0,A,b) starts at x0 and attempts to find a minimizer x of the function described in fun subject to the linear inequalities A*x ≤ b. x0 can be a scalar, vector, or matrix. Note...
