8/10/2023 0 Comments Matlab textscan delimiterTo sum up: fid = fopen('path/to/myfile') ĭata = textscan(fid,'%*s %s %s %f %f %f','Delimiter',',') ĭata now contains a cell array with each column in a cell. 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. ![]() that is also my first time doing communication with a serial device. 1 A cell array is an array that can store values of different types. ![]() 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). Finally, 'Delimiter',',' states that all commas should be interpreted as the delimiter between each column. i have a string with several values from an alicat as input and i want to cut into several values using textscan. %f means "interpret as doubles (floats)". ![]() The asterisk in %*s means "ignore this column". To do this, call: data = textscan(fid,'%*s %s %s %f %f %f','Delimiter',',') Ignore string string double double double To do so, get a file identifier of the text file with fopen: fid = fopen('path/to/myfile') Īssume for the data in this example, we want to ignore the first column "Data", read the date and time as strings, and read the rest of the columns as doubles, i.e. One may use textscan to read this quite fast. Date and time strings to numeric array fastĪssume you have formatted data in a large text file or string, e.g.Ordinary Differential Equations (ODE) Solvers.Fourier Transforms and Inverse Fourier Transforms.Finally, 'Delimiter',',' states that all commas should be interpreted as the delimiter between each column. to get '')ĮDIT Based no your comments, you want to do the conversion like this: % Read the data To do this, call: data textscan (fid,'s s s f f f','Delimiter',',') The asterisk in s means 'ignore this column'. If I output C, I get: Columns 1 through 6 It would be easier to have it as a "regular" array (pardon me for not knowing the correct nomenclature, I just started working with matlab). ![]() However, C is a cell array and this makes it harder to handle the contents of the file in matlab. So what I wanted the textscan to output was a 4 row cell array, the first row would have 6 cells representing the coordinates of the 6 regions for that specific row(in this case leaf tips). I have successfully imported a test file using the following: ftest = fopen('test.csv') Ĭ = textscan(ftest,'%f %s %f %f %f %f %f %f %s %s %f %f','Headerlines',1,'Delimiter',',')
