![]() Here, we will read vectors by their names to make it easy but you can change their names if you want. We can also define the number of rows and columns, if required but if the number of values in the vector are not a multiple of the number of rows or columns then R will throw an error as it is not possible to create a matrix for that vector. delete) all the rows where at least one column includes NaN, then just: try my snip function. A(:,:) reshapes all elements of A into a two-dimensional matrix. This has no effect if A is already a column vector. Replacing values within a row of matrix with a vector - MATLAB Answers - MATLAB Central Browse Replacing values within a row of matrix with a vector Follow 1 view (last 30 days) Show older comments connor on Vote 0 Link Commented: Jos (10584) on Accepted Answer: Wayne King Basicly I have a matrix with only 0 and 1's. ![]() A(:) reshapes all elements of A into a single column vector. How to change the values in a specific row of a matrix. ![]() So, in case that you want to ignore (i.e. A(:,:,p) is the pth page of three-dimensional array A. I mean, if my matrix is (3 5 2 4 7 1) So there are 6 elements in the matrix, and I need to change the numbers in the odd columns to 6 Like this: (6 5 6 6 7 6) Thanks for your help user3075653. Actually I would like to recommend a slightly different (and more general) approach. M magic (5) replacecolumn boolean ( 1 0 0 1 0) replace the 1st and 4th column. To convert a vector into matrix, just need to use matrix function. Better use M (isnan (M (:, 1)), :) which will remove any row that contains at least one NaN. I am looking for an elegant and simple way to replace a some columns in a matrix (specified by a logical array) with a given column vector, e.g: Theme. ![]()
