Read text file and store in .mat file

Assume i have the following values in a text file.

102

103

43.

i want to read this text file and store in a .mat file so that i can access the array of value.

Answer 1

[dpb]

data=importdata('yourfile.txt');

Use the data as is...

doc save % and friends to write/read .mat files...

If the data in the text file contain more formatting, etc., than just the simplest, then

doc textscan % and friends

help iofun

will give a list of all the choices (a veritable plethora from which to choose depending on what you have as the input format).

Thanks a lot for your reply. It works fine.

What if i use mixed data formats. (i.e)

16A

15E

0C

[dpb]

Presuming it's actually hex as it appears, use one of the formatted input functions such as

doc textread
doc textscan
doc fscanf

and the hex format descriptor string '%x'

If you know anything about C, that's helpful as Matlab uses its notation and i/o based on the C library. If not, the formatting descriptors are described fully in the fscanf documentation.

[shuchita bahadur]

when usinf importdata in Command line it works, not from within a script. The variable does'nt show in workspace.

[dpb]

In a script is the same as at the command line. If you mean a function m-file, yes, variables are local in scope within functions; to return the variable to the calling scope (command line or calling function), that function must have a return variable and the result of the read operation, whatever routine you use, returned to the caller via that variable.

See

doc function

for how functions work...
