That is the Index Vector block.

"Ldq" is a vector. The above math is: Out1=In1*Ldq(2)/Ldq(1)

you can create a variable named Ldq in the base workspace (and hope that it stays existing)
you can create a function or script that creates Ldq in the base workspace, and then invokes sim() to start the model
you can, if I understand correctly, create a function that creates Ldq in the function workspace, and then invoke sim() to start the model
you can create a Simulink variable named Ldq; https://www.mathworks.com/matlabcentral/answers/351732-define-variable-value-in-simulink-model#answer_415063
you can create a Simulink global variable; see https://www.mathworks.com/help/simulink/ug/use-global-variables-in-system-objects.html
you can set up a model initialization function callback that assigns Ldq in the base workspace
you can use a From Workspace block
you can use a From File block
