Reading Specific Columns of File

I have a data file like this;

20200001	95	53	66	29
20200002	40	29	9	69
20200003	3	33	45	94
20200004	48	52	79	17
20200005	91	65	76	51
20200006	10	17	30	64
20200007	94	85	66	82
20200008	87	67	14	89
20200009	12	100	51	58
20200010	50	51	49	40

And I need store every column seperatly like this;

student_number(1) = 20200001

student_number(2) = 20200002

exam_1(1) = 95

so far I done This;

fid = fopen('data.txt')
n = textscan(fid,'%*d %*d %*d %*d %*d','delimiter',' ')

But I am not sure it is reading data correctly an how can I acess any data ?

data = readmatrix('TheFileNameGoesHere.txt');
student_number = data(:,1);
exam_1 = data(:,2);

However you should consider instead doing

t = readtable('TheFileNameGoesHere.txt', 'variablenames', {'student_number', 'exam_1', 'exam_2', 'exam_3', 'exam_4'});

after which in your calculations instead of referring to exam_1 you would refer to t.exam_1

mean([t.exam_1, t.exam_2, t.exam_3, t.exam_4], 2)

Thanks for reply but I am getting an error;

error: structure has no member 'exam_1'

error: called from

main at line 3 column 1

After you do

t = readtable('TheFileNameGoesHere.txt', 'variablenames', {'student_number', 'exam_1', 'exam_2', 'exam_3', 'exam_4'});

Then what shows up for

size(t)
t.Properties.VariableNames

What shows up for

class(t)
