I've not been able to set the consant in the "constant" block. I used: set_param('dummy/Constant','x',50) but kept getting eroor "Constant block does not have a parameter named 'x'". 'dummy' is the model name.
Thanks.

I still got error: "Invalid setting in Constant block 'Constant' for parameter 'Value'. 'x' is in the place of the 'constant' block where the numeric value is given.

If x is a variable in the workspace, then you can use
set_param('dummy/Constant','Value','x')

Try
set_param('dummy/Constant','Value','50')
Note that the value is also a string.

x=50;
set_param('untitled/Constant','Value',num2str(x));
