want to make a number of row matrix from a single row matrix

i have a file with

line1:[1 2 3 4 5 6 7 8 9]

line2:[10 11 12 13 14 15 16 17 18] now i want to make a 3d matrix by

split line1 as[1 2 3],[4 5 6],[7,8,9]

and line2 as[10 11 12],[13,14 15],[16 17 18].

then i want to make 3 new matrixes as

mat1 =

        [1  2  3;10 11 12]

mat2=

       [ 4  5  6;13 14 15]

and

       [7 8 9;16 17 18]

Let A - your matrix (2 x 9)

A = reshape(1:18,[],2)';

out = reshape(A,2,3,[]);

reshaping each line will gives a single matrix in the specified dimension. but i want to make 3 row matrix from line1

you said: "then i want to make 3 new matrixes as

mat1 = [1 2 3;10 11 12]

mat2 = [ 4 5 6;13 14 15]

and [7 8 9;16 17 18]"

Your description is somewhat unclear to me. Do you mean

cat(3, reshape(line1, [3 3])', reshape(line2, [3 3])')
