State Space Block giving Dimensions of arrays being concatenated are not consistent.

I have a state space block in Simulink as follows:

A = [0 1 0 0 0; 1.8 -0.02002 -2 -0.00002 0; 0 0 0 1 0; 10 0.0001 -10 -0.0001 1; 0 0 0 -1000 -1000]
B = [0; 0; 0; 0; 1000]
C = [1 0 0 0 0]
D = [0]

When I pass an input to this block I get:

Invalid setting in '' for parameter 'A'.

Caused by:

• Error evaluating parameter 'A' in ''
• Dimensions of arrays being concatenated are not consistent.

I tested this in MATLAB and got no errors. I cant spot what I'm missing here, any help would be appreciated.
