I did this: Theme Copy mydata readtable ('mytable. I only have the issue that some values are negative numbers but not for example -9 but with a blank space like - 9. You can represent this data in MATLAB as tables, timetables, matrices, cell arrays, or string arrays. Text files often contain a mix of numeric and text data as well as variable and row names. ?fined 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, ',', '. I want to simply read the values in a csv file into an array. MATLAB can read and write numeric and nonnumeric data from delimited and formatted text files, including. EDIT1: to use textscan instead, the following code should do the trick or at least most of it. MyMatrix readmatrix('fileName.csv') You have to specify the file name and its extension inside the readmatrix () function to read the file. %textscan inputs work in pairs so your scanning the file using the format You can use dlmread it works in the following format M dlmread (filename,' ') 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. Read CSV File Using readmatrix () Function in MATLAB If you have numeric data saved in a CSV file, you can use the readmatrix () function to read the data into a matrix. %the formatspec represents what the scan is 'looking'for. Ive had the same problem with reading csv data in Matlab, and I was surprised by how little support there is for this, but then I just found the import data tool. M csvread ('filename',row,col) reads data from the comma-separated value formatted file starting at the specified row and column. The file can only contain numeric values. %rt is permission r for read t for open in text modeĬsv_file = fopen('D:\Dev\MATLAB\stackoverflow_tests\1.csv','rt') Description M csvread ('filename') reads a comma-separated value formatted file, filename. 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. You can use dlmread it works in the following format 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.
