![]() that is also my first time doing communication with a serial device. i have aseen a very old script, that used strread, but there is an information its not available for so long, so i write my own script now and update everything else accordingly (serial to serialport and so on). If trailing delimiters should invoke the missing-contents behaviour (your interpretation) then that would imply that the 123 should be accepted by the first time %f is processed, then the abc should be accepted by the first time %q is processed, then the empty field at the end of the line should be accepted and turned into nan by the second time %f is processed, then the 456 should be accepted and turned into character vector by the second time %q is processed, then the def should trigger a format mismatch the third time %f is processed, stopping the scanning and leaving def, in the buffer. i have a string with several values from an alicat as input and i want to cut into several values using textscan. For example if the input were 123,abc,456,def, and the format were %f%q then with the current behaviour that would generate. For example: a,142,5 aa,3,0 abb,5,0 ability,3,0 about,2,0 I want to read the file and put the words in one variable, the first numbers in another, and the second numbers in another but I am having trouble with textscan. ![]() This question assumes that all you have is numerical values, so a cell array is indeed redundant, and it can be converted into a matrix, which is much easier to manipulate. Here you have a cell array that stores both columns of numbers and strings. ![]() I can use h as a delimiter, but I cannot use. 1 A cell array is an array that can store values of different types. If trailing delimiters should invoke the missing-contents behaviour (your interpretation) then that would imply that the 123 should be accepted by the first time %f is processed, then the abc should be accepted by the first time %q is processed, then the empty field at the end of the line should be accepted and turned into nan by the second time %f is processed, then the 456 should be accepted and turned into character vector by the second time %q is processed, then the def should trigger a format mismatch the third time %f is processed, stopping the scanning and leaving def, in the buffer.Yes, textscan could have been designed to set an internal flag indicating that a delimiter had been seen before the current position, but I am not sure that would meet with expectations. txt file with rows consisting of three elements, a word and two numbers, separated by commas. I want to use h as a single delimiter to extract the letters after h with textscan function. ![]() So in your example when processing 'a,b,' with q it first processes the a as part of the q format, and then eats the delimiter that is there, leaving 'b,' in the. Finally, 'Delimiter',',' states that all commas should be interpreted as the delimiter between each column. Well, it tells us that after textscan finishes processing the format, it examines the input stream, consuming Whitespace and up to the first copy of the Delimiter, and then stops. For example if the input were 123,abc,456,def, and the format were %f%q then with the current behaviour that would generate. To do this, call: data textscan (fid,'s s s f f f','Delimiter',',') The asterisk in s means 'ignore this column'. Yes, textscan could have been designed to set an internal flag indicating that a delimiter had been seen before the current position, but I am not sure that would meet with expectations.
