Hi guys! Well imagine that I have two mat files one is a.mat and the second is b.mat file. Now i want to save them into another ab.mat file for example in such a way

save (ab.mat, 'a.mat', 'b.mat')

But it says that a.mat and b.mat are not valid variables so any ideas would be a great job for me ;)

在 MATLAB Online 中打开

aLoad = load( 'a.mat' );
bLoad = load( 'b.mat' );
save( 'ab.mat', '-struct', 'aLoad' );
save( 'ab.mat', '-struct', 'bLoad', '-append' );

works. It's probably neater to merge the structs and do a single save, but I couldn't remember off the top of my head how to do that so if this is a one-time operation then that solution works fine.
