saving plots and reopening them

Hi everyone, when i save a plot using the function h=sprintf('plot%d.jpg,k) it stores the figure but when i try to re open the figure it happenes to be a text file with the text not being english but like windings. Why is this? thanks ahead of time.

Figures stored in *.ppg files can't be opend in MATLAB. If you plan to reopen figures in MATLAB, Y should save them in *.fig files.

ppg ? PowerPoint Graphics files? The poster did not say anything about PPG files or PowerPoint. The code uses jpg (JPEG) as the extension, and JPEG files can be read into MATLAB using imread()

Please show the section of code you are using to do the saving.

Plots are not normally saved as text: they are normally saved as binary. There are a few text formats for plots, but JPEG in particular is a binary format.
