how to load this into matlab from a txt file:
[1 2 1 E A Iy Iz Ix J
2 3 2 E A Iy Iz Ix J
3 4 3 E A Iy Iz Ix J]
the problem is that the letters E A Iy Iz Ix J ----> gives NaN when I load it into matlab

Rik probably he would need the letters for his symbolic computations. So the solution is to use textscan(...) as KSSV suggested.

Since the data type of all values is not same, try importing it as cell array
data = readcell('testload.txt')

As Madhan mentioned that you might want to load it as symbolic, you may try
str = fileread('test.txt');
words = regexp(str, '\w+', 'match');
idx = cellfun(@(x) isnan(str2double(x)), words);
M = eval(str);
