채택된 답변:Walter Roberson Suppose I have a matrix A and suppose I want to create a new matrix from 1st, 3rd, and 4th column of A. Is there any compact way to do this? 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
I want to take out a column in the matrix by searching in the first row ThemeCopy clc, clear frequency = linspace(1,20,20); amp = randi([-100,-60],10,20); matrix_test = [frequency;amp] [my_vec_For_example_num_11] = find(matrix_test==11) % I want to enter a numbe...
So, here's my task: I have a matrix that is 115x12 (years and months... not that it matters!) I want to take row 2 and attach it at the end of row 1, and row 3 at the end of that, etc., to make one long vector (1x1380) in another va...
I am looking for a efficent method to extract data from this matrix by searching via coordinates, for example I have x=45 and y=105. I want to find the row where x=45 and y=105 are located and extract all the data from that row. Thanks 2 Comments Kevin Holly on 3 Oct 2022 ...
● M = csvread('filename', row, col, range),读取文件filename 中的数据,起始行为 row,起始列为col,读取的数据由数组 range 指定,range 的格式为:[R1 C1 R2 C2],其中R1、C1为读取区域左上角的行和列,R2、C2为读取区域右下角的行和列。
I have a matrix as below. I want to build a new matrix based on maximum value at row 4 element. Here column 5 is the index matrix, column 1 is the year, column 2 is month and column 3 is date. I want to extract the row with maximum value in column 4. Fo...
%%* odd and even rows in a matrix a=linspace(1,20,20) a=a' a_even = a(2:2:end,:) a_odd=a(1:2:end,:)
This MATLAB function computes the vector of decision variables corresponding to the values X1,...,Xk of the matrix variables in the LMI system lmisys.
Example 2: Using DLMREAD to extract the first 3 columns of the last 3 rows % This reads in the first 3 columns of the last 3 rows of % the data file 'sample_file.txt'into the matrix, D_partial. % 读文件 'sample_file.txt' 前3列后3行,到矩阵D_partial. ...
