I have a txt file that looks something like this:
>01 01 2020
A 1 2 3
B 4 5 6
C 8 9 0
>02 01 2020
A 3 4 5
B 7 6 5
C 5 7 6
I need matlab to read the file, and then make a matrix for the date (after the >) and the data in each date (a col for A, B, C)
i read the file using fopen, and i set line=fgetl(txtfile) but im not sure how to make it read a new row in the matric everytime there is a '>', or place the value of specific columns in the txt file in a column in the matrix.
Im sorry if this question is very stupid, i just started working with matlab and im facing a lot of difficulties.

It sounds like you need a loop. Inside that loop you can check if the first character is < and increment a row counter.

Try this
f = fopen('data.txt');
data = textscan(f, '%c%f%f%f\n');
fclose(f);
data = [data{2:end}];
data.txt is attached.
