We will create a matrix from two smaller matrices, as follows:
A = np.eye(2) print "A", A
The identity matrix looks like this:
A [[ 1. 0.] [ 0. 1.]]
Create another matrix like A
and multiply by 2
:
B = 2 * A print "B", B
The second matrix is as follows:
B [[ 2. 0.] [ 0. 2.]]
mat
function; only, you can use matrices instead of numbers.print "Compound matrix ", np.bmat("A B; A B")
The compound matrix is shown as follows:
Compound matrix [[ 1. 0. 2. 0.] [ 0. 1. 0. 2.] [ 1. 0. 2. 0.] [ 0. 1. 0. 2.]]
