How to use saveas() to save a .mat or .txt in specific directory on ubunto

I have tried:

saveas(keys ,keyname);
save(keys ,keyname ,'-mat');
save(keys ,keyname);


where keys is a 3006x4104 matrix of the class double.
I tried to use some casting so I would save it as txt file

keys

for keyname I tried - ./newdronephotos/1880key.mat
and newdronephotos/1880key.mat.

keyname

./newdronephotos/1880key.mat

newdronephotos/1880key.mat

It's not working.
In particular, when I'm trying saveas(keys ,keyname);
it's starting to do some processes and then print the error message:
Error using saveas (line 88)
Simulink object array must be a vector

saveas(keys ,keyname);

Error using saveas (line 88)
Simulink object array must be a vector

save

saveas

Actually, I just succeeded to solve my own problem.
The function save() expect to have a string of the name of the desired variable.
For example:
Instead of -
save(keyname ,keys);
I needed to write-
save(keyname ,'keys');
