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..

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)
