Good morning,
I'm sure there's a built in function but I can't find it. I want to create static positioning for information being sent to a text document in MATLAB. For example:
height weight age favorite number
------------------------------------------------------------
60 140 24 9
30 45 3 10000000
48 100 9 19
9 7 1 1
currently, i'm just doing an fprint call with padded spaces to get it lined up, but the issue arises where having different length numbers causes the alignment to be off, like so:
height weight age favorite number
------------------------------------------------------------
60 140 24 9
30 45 3 10000000
48 100 9 19
1 7 1 1
Thanks in advance.
here's an example script that'll show what I mean:
fid1 = fopen('stackoverflowtest', 'w');
if fid1 < 3,
error('ERROR');
end;
fprintf(fid1, 'height weight age favorite number \n');
fprintf(fid1, '------------------------------------------------------------ \n');
height = 0;
weight = 10;
age = 100;
number = 3;
for i = 1:100
fprintf(fid1, "%d ', height);
fprintf(fid1, "%d ', weight);
fprintf(fid1, "%d ', age);
fprintf(fid1, "%d \n", number);
height = height + 3;
weight = weight + 6;
age = age - 1;
number = number + 23;
end
You can do this with the fprintf format specification, for example %-15d.
Here, the - is a flag which specifies left justification, and the 15 specifies how much space to leave around the representation.
We can reproduce your example with
A = [60 140 24 9
30 45 3 10000000
48 100 9 19
9 7 1 1];
fprintf('height weight age favorite number \n'),...
fprintf('------------------------------------------------------------ \n'),...
fprintf('%-15d %-15d %-12d %-15d \n',A')
which displays
height weight age favorite number
------------------------------------------------------------
60 140 24 9
30 45 3 10000000
48 100 9 19
9 7 1 1
EDIT: You can store this data as a table:
height = A(:,1)
weight = A(:,2);
age = A(:,3);
favourite_number = A(:,4);
tab1 = table(height, weight, age, favourite_number);
disp(tab1);
This prints to screen
height weight age favourite_number
______ ______ ___ ________________
60 140 24 9

but I'm not sure how to save this representation to a file.
