Also, there might be some issues with formatting in Excel. There are several ways to write to a file. NOTE: if you are using MATLAB 6.5 there is no 'xlswrite' command (that I'm aware of). The xlswrite command below creates a spreadsheet called filename.xls in the current directory from the variable g: You can specify the path to a file but, this can get messy. Make sure that the file you choose is in the same directory were you save your M-files (usually the work directory) otherwise you get an error. You can then manipulate the array g any way you want.

This line of code reads filename.xls (from the current directory) and places it in an identical array inside MATLAB called g. To use the xlsread function use the syntax: MATLAB makes it easy to read from an Excel spreadsheet. I cover the command line first since it is often necessary to import the data while an m-function is being evaluated. Since analyzing data is one of the more common motivations for using input output I will start with reading and writing from a spreadsheet. > save('mySave.mat', 'newData*', '-append')Įxcel Spreadsheets I/O Save all myData variables to an ASCII file.

Save all myData variables to a mySave.mat file compatible with version 6 of MATLAB.Save all myData variables to mySave.mat.Save just the variables myData1 and myData2 to mySave.mat.Save all workspace data to the file mySave.mat in the current directory.The save command is used to save workspace data to a file. Get a cell array of variables in saved file.Load just the variables myData1 and myData2.Load all variables from the file mySave.mat into the current workspace.The load command is used to load data from a file into the current workspace. The files can be text, images, and even audio files. Load(filename) can loads data from filename. Importdata(filename) can loads data into array. The function that usually are used to import data into MATLAB : importdata(filename) This type of files storing the live scripts/live functions that uses the Live Code file format. This format were just introduced on MATLAB version R2016a. mat can be supported by the older version off MATLAB) mat files: Standard MATLAB files (Most functions in. There are two file types used by MATLAB namely. 5 MATLAB File I/O: from the Graphical User Interface.Read and manage data from a collection of text files.
