Let's say that I have the model

and the data
X=[1 1 1 1 1; 0 1 2 3 4]';
Y=[1 4 3 8 9; -1 -1 2 3 2]';
How can I fit and evaluate this multivariate data in Matlab?

X(:,1) consists of constants, so I assme you want to regress:
a1 = regress(Y(:,1),X);
a2 = regress(Y(:,2),X);
If you really want to regress Y(:,1) on X(:,1) you will only estimate the mean (since X(:,1) consists of ones). Note that B(0,1) and B(1,1) are collinear, in that case.

X=[1 1 1 1 1; 0 1 2 3 4]';
Y=[1 4 3 8 9; -1 -1 2 3 2]';
beta = mvregress(X,Y)
