Converting text file to array

Hi.

I want to convert the text file (file attached below) into array of size 4X6. The array should not include the first row (containing characters).

Please help

If you have R2019a or later versions, the best approach is to use readmatrix, as Walter has specified.

Otherwise, readtable is the obvious choice.

format long g
arr = readmatrix("WallContacts.txt")

arr = 4×6

1.0e+00 * -0.00275786 0.24992 0.449027 845.871 0 0 -0.00421111 0.455012 0.190379 1260.68 0 0 -0.00385227 0.775165 0.177235 1166.12 0 0 -0.00300194 0.085385 0.172096 905.685 0 0

Hi mukesh,

I understand that you are trying to import text file data as an array.

In order to achieve this, you can follow below steps:

• Since, the data in the text file is in a table format. You can import the data as a table using "readtable" function and perform the desired operation on the table itself.

    % import the text file as table
    tbl = readtable("WallContacts.txt");

• Once you have imported the data as a table, you can convert it to an array using "table2array" functions as shown below.

    % convert it into multidimensional array or matrix
    arr = table2array(tbl);

Hope this resolves you query!!
