We can view the variables currently in the Workspace by typing
» who Your variables are: ans x y z leaving 621420 bytes of memory free.
More detail about the size of the matrices can be obtained by typing whos.
We can find the size of a matrix or vector by typing
» [m,n]=size(x) m = 1 n = 6
where m represents the number of rows and n represents the number of columns.
If we do not put place arguments for the rows and columns, we find
» size(x) ans = 1 6
Since x is a vector, we can also use the length command
» length(x) ans = 6
It should be noted that MATLAB is case sensitive with respect to variable names. An X matrix can coexist with an x matrix.
Sometimes it is desirable to clear all of the variables in a ...
