Type help load to see how data is imported to Matlab. Briefly, the data file must contain n rows with m columns of data in each row. If the file is named foo.dat, then type load foo.dat. Matlab will call the data foo.
>> load foo.dat >> foo foo = 1 2 3 4 5 6 7 8 9 10
Type help save to see how data is exported from Matlab to disk. To save the foo data in a file called foo2.dat, follow the commands below.
>> help save SAVE Save workspace variables to disk. SAVE fname saves all workspace variables to the binary "MAT-file" named fname.mat. The data may be retrieved with LOAD. Omitting the filename causes SAVE to use the default filename "matlab.mat". SAVE fname X saves only X. SAVE fname X Y Z saves X, Y, and Z. The wildcard '*' can be used to save only those variables that match a pattern. SAVE fname X Y Z -ASCII uses 8-digit ASCII form instead of binary. SAVE fname X Y Z -ASCII -DOUBLE uses 16-digit ASCII form. SAVE fname X Y Z -ASCII -DOUBLE -TABS delimits with tabs. SAVE fname X Y Z -V4 saves a MAT-file that MATLAB 4 can LOAD. SAVE fname X Y Z -APPEND adds the variables to an existing MAT-file. Use the functional form of SAVE, such as SAVE('fname','var1','var2'), when the filename or variable names are stored in strings. See also LOAD, DIARY, FWRITE, FPRINTF. >> save foo2.dat foo -ascii
