What I want to do is to find and remove all negative values in the 2 column of each matrix within the array and its corrosponding row, leaving only the postive ones. The codes with I have used are unable to achieve this as there are always problems involving the exceedance of array bou...

3 % RANK(A) provides an estimate of the number of linearly 4 % independent rows or columns of a matrix A. 5 % RANK(A,tol) is the number of singular values of A 6 % that are larger than tol. 7 % RANK(A) uses the default tol = max(size(A)) * norm(A) * eps. 8 9 s =...
Remove incomplete rows from a table with multiple data types. First, create a table whose variables includecategorical,double, andchardata types. A = table(categorical({'';'F';'M'}),[45; 32; NaN],{'';'CA';'MA'},[6051; 7234; NaN],...'VariableNames',{'Gender''Age''State''ID'...
MATLAB Online で開く Hello, 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 ...
clc clear a=1; m=3; for i=1:m %理解此处的m不是向量，是循环时的某一个固定值 b(i)=a*i %得到的b值保留前一个循环中计算的值。是一个随着i变化的向量，loop1时向量中有1个元素；loop2时有2个元素，分别是loop1中值和loop2中的值。这种情况下，不会覆盖loop1中参数。

Is there an easy way to remove ALL rows that are NOT unique? For example, how would I get B from A? A = [1 2; 1 3; 1 4; 1 2; 1 5]; B = [1 3; 1 4; 1 5]; I could do this in a loop, but there seems like there must be a more elegant way. I've looked at ...
