**how to get first and last column of a matrix in MATLAB?**

I'm having a hard time in trying to get rid of linearly dependent columns of a matrix on matlab. I was trying to run this code . for i=2:22 if rank(D(:,1:i))==i-1 D(:,i)=[]; end end for a 30x30 matrix with rank 22, which means that I have to get rid of 8 linearly dependent columns. In this code I am just getting rid of the first ld column and the the following one that is not ld. Does anyone... In your case a much more robust solution would be to use structures, where you can include fields for each kind of data (e.g. Process type, Flow data, Temperature data, Notes, Units, etc), or cell arrays.

**Inserting a column in a matrix without deleting any column**

23/11/2017 · In this video on How To Interchange Row and Column of Matrix in MATLAB of Basics of MATLAB Programming, we will get deep learning about How To Interchange a row and a column of a matrix in MATLAB... While the first version is more mechanical translation of "add a new column consisting of zeros" from English to Matlab, the second method is faster and looks much leaner (more "matlabish"). The decision which version is "better" depends on your needs.

## How To Get Second Column Of A Matrix In Matlab

I want to compare the first column of A with the matrix T and calculate the percentage that this column contains the same value than the matrix T. the next step is to compare the second column of A with T and add the percentage that this column contains some values missing compared to the first column. the final step is similar than later but using the third column.

- While the first version is more mechanical translation of "add a new column consisting of zeros" from English to Matlab, the second method is faster and looks much leaner (more "matlabish"). The decision which version is "better" depends on your needs.
- I have the matrix as follows. a = 1 3 2 5 3 2 4 8 5 9 I want to sort the second column in the a matrix. I want the corresponding rows of column one to be printed as follows :
- If I were to assume that the column e is the second column and the name of the matrix it's in is matrix1, then: RequiredColumn=matrix1(1:end, 2); As you can see, in the first part of matrix1, I ask MATLAB to recall all the rows; from first row to the last row.
- where the x1 and y1 come from one column, and the x2 and y2 come from the second column. If that doesn't work, then post your data sand indicate which elements of the array you want a …
