hello there,

I am very tired and I would need to read a string like this

tline = 'CHTRS95 46.521464753 6.567893633 460.487'

tline is a char, I want to put the first word in a string and the three numbers in a double.

All using this function:

sscanf(tline, ' %f %f')

(it is somehow wrong,

I get :"

Unable to perform assignment because the size of the left side is 1-by-2 and the
size of the right side is 0-by-0

.")

split = textscan(tline, '%s%f%f%f');
txt = split{1}
numbers = cell2mat(split(2:end))
