How to pad a matrix with a vector instead of a single value

How would I go from two vectors and a matrix to a larger matrix surrounded by these vectors on the top and right side?

xcoeff = [0,0.25,0.5,0.75,1]

ycoeff = [0,0.25,0.5,0.75,1]

Tinside = [0.42 0.54 0.42

0.54 0.70 0.54

0.42 0.54 0.42]

And result in the 5x5 matrix. The top left corner is not that important becasue it will always be 1*1 which is just equal to 1, so they do not have to be multiplied. It could just be a 1.

Tfinal =

[0 0.25 0.5 0.75 1*1

0 0.42 0.54 0.42 0.75

0 0.54 0.70 0.54 0.5

0 0.42 0.54 0.42 0.25

0 0 0 0 0 ]

Not sure if it's for general cases:

 Tfinal=toeplitz(xcoeff,ycoeff);
 n=numel(xcoeff);
 [M,N]=size(Tinside);
 Tfinal(n-M:n-1,n-N:n-1)=Tinside;
 Tfinal(:,1)=0;
 Tfinal(end,:)=0
