Let's say I have a matrix A (Nx2) which holds pixel indices of pixels in matrix B. I would like to use matrix A and replace the pixels in matrix B with some value (e.g.255) the easy way would be to use a For loop: B(A(i, 1), A(i, 2)) = 255; Is it possible to ...

I'm trying to index a large matrix, with the goal of finding/indexing the first value to meet a threshold. Right now I'm doing it in a loop, but it's rather slow. For example: a=[10 13 14 15 16;... 11 12 15 16 17;... 3 5 8 9 12]; threshold=11.5; I want it to r...
MATLAB Online에서 열기 Ran in: For matrix R, sort(R) sorts each column and indsort are row indices. To reproduce the sorted matrix, you can convert those row indices into linear indices. Here are a few ways to do that: 테마복사 R = rand(10,10) R = 10x10 0.3822 ...

A row matrix B=[21 43 23 65]. Now I want to sort them in ascending order and also want the order of their location. How to do this??? I want the output file look like: [21 23 43 65] and [1 3 2 4]. 0 Comments Sign in to comment. ...
在MATLAB中,索引通常用于访问数组或矩阵的元素。错误的索引使用可能包括越界索引、使用非整数索引等。例如,如果你尝试访问一个矩阵的第5行第0列的元素(matrix(5,0)),这将会导致索引错误,因为列索引从1开始。 确保你的索引值在有效范围内,并且适用于你正在操作的数据类型。 确保在定义符号函数时遵循正确的语法: ...
