hello everyone,
i have three columns with 25 rows each. Now I want to merge all the three columns to one in a way that the first three rows will be the 1st values of all the three columns.
for ex: col_1, col_2 col_3 I need New merge col
25 22 23 25
26 25 20 22
24 28 30 23

Use this
X = reshape(X', [75, 1])

Works also if the number of lines or columns is different to 25x3:
a = [col1 col2 col3]
b = reshape(a',[],1)

I will proceed in the following way-
1) Merge col_1, col_2, col_3 into a single matrix.
2) Reshape the transpose of the array.
The following code does the same-
res = reshape([col_1 col_2 col_3].', [], 1)

Are your col_1, col_2 and col_3 variables stored as column vectors or row vectors?
