%defined above and with a semicolon delimeterĬ = textscan(csv_file, formatSpec, 'Delimiter', ' ') ĮDIT2: to replace the comma with a dot and convert to a integer of type double: = size(C) Ĭonverted_data = str2double(strrep(A, ',', '. Theme Copy T readtable ('myfile. The readtable function automatically detects the header and the number of lines to skip. %textscan inputs work in pairs so your scanning the file using the format I have a csv file with data that goes like: 3 2 91 83 17 3 2 86 84 4 3 2 90 83 162 (there's a total of 7000 rows) I need a way to read this into an. Question: MATLAB: Read the saved CSV file, take the average and standard deviation of each ROW. To import data from a CSV file into MATLAB use the readtable function. %the formatspec represents what the scan is 'looking'for. %rt is permission r for read t for open in text modeĬsv_file = fopen('D:\Dev\MATLAB\stackoverflow_tests\1.csv','rt') The filename is a string with the full path of the file unless the file is in the current working directory in which case you can just type the filename.ĮDIT1: to use textscan instead, the following code should do the trick or at least most of it. The file from where the read table function can read the data can be a text file, a comma-separated or csv file, or some other excel workbook. csvread imports any complex number as a whole into a complex numeric field, converting the real and imaginary parts to the specified numeric type. You have a problem that your file (at least the fixedtest.csv that you posted) is UTF-16 Little Endian, which is an encoding format that MATLAB does not support. You can use dlmread it works in the following format There is an option called Import under the tab named File in MATLAB. Introduction to Matlab readtable Read table function in MATLAB is used to create a new table by reading data present in the form of columns in a file. When the csvread function reads data files with lines that end with a nonspace delimiter, such as a semicolon, it returns a matrix, M, that has an additional last column of zeros. once that is done you can click import selection beneath the arrow and generate a script or function that will follow the same rules defined in the import data window. EDIT3 (ACCEPTED ANSWER): Using the import data button in the variable section of the home toolbar it is possible to customise how the data is imported.
