how to create a mat file of a given image with the same file name?

t=imread('a.jpg') is the code. my output mat file should be a.mat what is the code.

Answer 1

[Lisa Wu]

t = imread('a.jpg ');
save('a.mat','t');   % save the varible t to a.mat 

Usage of function SAVE is :

save (FILENAME ,VARIABLES)

and both filename and varible should be a string ,

for example ,filename shoule be 'filename.extension ';

Know more about SAVE ,you can type Help save in command window

if the file name is a.jpg, then i should get a.mat... if the file name is castrol.jpg, then i should get castrol.mat... file names are random. user can select any image downloaded from google.main objective is to create a mat file automatically with the same file name itself..

Answer 2

[Yao Li]

try

strcat()

to define the name of the mat file

For example, filename='a';

matfilename=strcat(filename,'.mat');

save(matfilename,'t');

You may also have to create a function to remove the extension of the figure name (.jpg)
