Passing values from Matlab to Simulink

Hi,

I am trying to assign a set of variables values in matlab, and then pull them through into Simulink, but having problems getting the correct value.

For example, in Matlab i have defined a constant T such that

T = 0.2

In Simulink, i have then created a Constant block where the variable is T, but when i run the model i find that the Constanant block returns a value of 2 & 1, rather than the 0.5,

Can someone advise what i am doing wrong?

Start a new model, drag a Constant block and Display block. Connect them, specify the Constant value as T and simulate.

Thanks for the answer - this is what i have been doing, but for some reason the value of T is not being brough through correctly, and it looks like the value of T is an array dimension i.e. [2 1]
