How to read comma separated .txt file in MATLAB ?

I would use the settings available in readmatrix to make the '=' a delimiter. That will treat the '#A-R' as another column of data. I would then use the 'Range' input to skip the first column.

data = readmatrix("sampleData.txt",'Delimiter',{',','='},'Range','B1')
data = 3×3
    -6    20   304
    -6    22   311
    -3    22   315

Hi @M

Try strsplit() or split() on rows and string array '#A-R' as delimiter. It divides each element of input at the specified delimiters. If you wish to separate number values, use strsplit() or split() with '#A-R=' and ',' as delimiters. Here are several examples:

temp = "#A-R=-6.00,20.00,304.00";
columns = strsplit(temp, "#A-R=")
columns = 1×2 string array
    ""    "-6.00,20.00,304.00"
sepColumns = strsplit(temp, ["#A-R=", ","])
sepColumns = 1×4 string array
    ""    "-6.00"    "20.00"    "304.00"
