Aug 9, 2010 · I would like to ask a question about Matlab program. I have vector a a = [1 2 3 4 5 6 7 8 9 10 11 12]; I would like to convert vector a to 2D array. Normally, I use this code to convert it. m =1; for i=1:4 for j=1:3 b(i,j) = a(m); m=m+1; end end Then b …

Feb 23, 2017 · After executing the above piece of code, I got x1 (64*1) 1D array and y1 (64*1) 1D array as new coordinates. Now I want to convert x1 and y1 into (8*8) matrix with new coordinates i.e. (x1,y1).

Feb 5, 2010 · Does anyone know if there is a way to produce a 2D array from a 1D array, where the rows in the 2D are generated by repeating the corresponding elements in the 1D array. I.e.: 1D array 2D a...

C = cat(dim,A1,A2,…,An) concatenates A1, A2, … , An along dimension dim. You can use the square bracket operator [] to concatenate or append arrays. For example, [A,B] and [A B] concatenates arrays A and B horizontally, and [A; B] concatenates them vertically.

Aug 21, 2013 · The function tridiagonal (n) gives values of x in a 1 dimensional array. I want to assign it to 2 dimensional array of w (s,t). However it shows error saying "Undefined function 'x' for input arguments of type 'double'."

Dec 9, 2013 · I have a 2D array and I want to create a 1D by MATLAB, satisfying the requirement that each element of the 1D output was created by the value of a given index into the 2D array. Example 2D array is A=[2 4 6; 1 9 7.3 4 5] And indexes for the 1D array X=[1;2;3] Y=[1;2;3] I want to store the 1D array with elements determined by

B = reshape(A,sz) reshapes A using the size vector, sz, to define size(B). For example, reshape(A,[2,3]) reshapes A into a 2-by-3 matrix. sz must contain at least 2 elements, and prod(sz) must be the same as numel(A).

Oct 3, 2021 · I need to get this 1-D array over to a 2-D array based on the first altitude level (or alternatively on a 3D array for lattitude, longitude, and altitude). I start with converting linear indices to subscripts, but once I do so, how do I broadcast the indexed-based reflectivities on a 2D array of longitude and latitude?

After executing the above piece of code, I got x1 (64*1) 1D array and y1 (64*1) 1D array as new coordinates. Now I want to convert x1 and y1 into (8*8) matrix with new coordinates i.e. (x1,y1).

Sep 13, 2015 · Here's a function that's supposed to do what you want: concatenate a row vector to an array regardless of size. This function will check the dimension along the second axis of input and output array and pad zero to whichever one that is smaller so they can be concatenated along the first axis.
