I want to sort matrix A using the values in the column matrix B to have the C below: C=[A=[3 3 6; 5 5 9; 7 9 4; 2 2 5; 1 1 4; 8 1 2; 4 4 8; 6 8 5; 9 3 4] I have tried the code below, but it seems not to work ...
I am trying to remove specific rows in an array based on the values in the second column, but when it removes those rows, it also removes the first column. What I have: data = 1 0.002 2 0.304 3 0.220 . . . . 1207 0.120
I think one possibility would be B = ceil(10 * tiedrank(A) / length(A) . What do you think? Are there any issues with this? Also, more generally, if I have a matrix A [m x n] and I want to create a matrix B also [m x n], in which each column of B should have the ...
小提示:在MATLAB的内部资料结构中,每一个矩阵都是一个以行为主(Column-oriented )的阵列(Array)因此对於矩阵元素的存取,我们可用一维或二维的索引(Index)来定址。举例来说,在上述矩阵A中,位於第二列、第三行的元素可写为A(2,3) (二维索引)或A(6)(一维索引,即将所有直行进行堆叠後的第六个元素)。 此外,...
matlab排序之sort()函数sortrows()函数,sortrows()函数的格式:sortrows(A,column)A是一个矩阵,如果没有第二个参数column,则默认按照第一列升序排列,如果遇到重复数字,则按照第二列升序排列,依次类推。。。如果存在第二个参数column,则按照指定的列排序,当指定的列

What I want to do is create an array out of A that starts a new column every time there's a gap: ThemeCopy CELL = {[1; 2; 3; 4], [6; 7; 8; 9; 10], [12; 13; 14; 15; 16; 17], [19; 20]}; I wrote a loop that does just that, but because A is so ...
Create a 2-by-1-by-3 array and remove the singleton column dimension to form a 2-by-3 matrix. y = rand(2,1,3) z = squeeze(y)y(:,:,1) =0.8147 0.9058y(:,:,2) =0.1270 0.9134y(:,:,3) =0.6324 0.0975 z = 0.8147 0.1270 0.6324 ...
% out - structure array that contains the following fields: % dd - unfiltered data densities at (x,y) % ddf - filtered data densities at (x,y) % radius - area used in 'circles' and 'squares' % methods to calculate densities
() outputs them as complex numbers with negligibly small imaginary parts to eliminatethis discrepancy, we will need to run the functionL=real(L);on the vector L.Then, we will sort the entries of L using the MATLAB commandL=sort(L);To output vector L correctly, you will go through ...
