converting column of data to matrix plane

Hello,

I have a data file that has the following shape:

x y z U V W

-0.026 -0.108 0.1 -4.4822257E-02 5.4139438E-01 1.1798316E-10

-0.025 -0.108 0.1 -4.9442114E-02 6.5561204E-01 6.8515270E-11

-0.024 -0.108 0.1 -1.2523164E-01 5.4269489E-01 -9.1736493E-11

-0.023 -0.108 0.1 -1.9679146E-01 4.1256618E-01 -2.4873436E-10

-0.022 -0.108 0.1 -2.4292102E-01 2.9788454E-01 -3.5452176E-10

where it represents the velocity values of a plane (67*67), every 67 row y changes.

I want to convert a single column of the velocity value (U, V or W) to a matrix that represents the actual plane (67*67), by taking every 67th line and paste it in a new row.

Any way to do it? the original data file is included if needed.

Thank you!!!

Found:

This is an example:

% Define the column

A = [1;4;7;10;13;16];

% Define the value of n n = 3;

% Initialize an empty matrix to store the new submatrices B = [];

% Loop through the rows of the column A

for i = 1:n:size(A,1)

% Extract every nth row of the column A

subcol = A(i:i+n-1);

% Convert the subcolumn to a matrix

submat = reshape(subcol,n,1);

% Append the submatrix to the new matrix B

B = [B submat];

end
