Parse through .txt file to create vector

I have a .txt file of STM information that I need to create vectors for. The data comes out (see below) from a fortan code I have on VS and I can import as a .txt file.

I need a (n,1) vector

Each row in .txt file has 6 numbers to input into vector

0.185167780E+010.530606201E-020.255950360E-010.111319395E+010.795404102E+03-.200248462E+02

For example row 1, I need first 6 elements of vector to be (each number string has exactly 15 characters)

0.185167780E+01

0.530606201E-02

0.255950360E-01

0.111319395E+01

0.795404102E+03

Thanks for any help

Use the fixedWidthImportOptions function and readmatrix (since there are apparently no header lines or variable names) —

opts = fixedWidthImportOptions('NumVariables',6, 'VariableWidths',[15 15 15 15 15 15], 'DataLines',1);
% T1 =  readtable('JG_20231103.txt', opts)
A1 = readmatrix('JG_20231103.txt', opts)

A1 = 6×6 cell array
    {'0.185167780E+01'}    {'0.530606201E-02'}    {'0.255950360E-01'}    {'0.111319395E+01'}    {'0.795404102E+03'}    {'-.200248462E+02'}

I created the file by pasting the original matrix into Notepad and saving it as a .txt file.

Yes this works, thank you!
