Why do I get the error "Unbalanced or unexpected parenthesis or bracket?"

I wrote an electrical capacitor code for importing to the simscape component from the simulink and proceeded with the compile, and an error such as "Unbalanced or unexpected parenthesis or bracket."

The following is a rough structure of the code I used.

component mycapacitor < foundation.electrical.electrical



parameters


A[7] = {560 , 320, 6690,9400,3400,9600,6700} ;
B[7] = {1.09, 1.14, 1.57, 4.75, 2.02, 1.041, 6.00}; 

end

variables
vc = {value = { 0, 'V' }, priority = priority.high}; % Capacitor voltage
end

intermediates
power_dissipated = r*i^2+g*vc^2; 
end

equations
assert(c>0)
assert(g>=0)
assert(isfinite(g))
assert(r>=0)
assert(isfinite(r))

for i = 1:m
    v == i*A[i] + vc*B[i];
    i == c*vc.der + g*vc;
end

end

[SL: Formatted code as code.]

An error occurred in A[7] and B[7] of the above code. The language is known based on the modelica code. I used most of the array methods in the modelica code, but I got the same error. What's the problem??

I don't understand if you want help on modelica code or to convert it in matlab code

Thank you for your question. To use the simscape component block, import the ssc file and proceed with the compilation. At this time, it should be written based on the modelica code, so I think I should get help with the modelica code.

As far as I can see, Simscape uses () for indexing, not []

Thank you for your reply. As a result of changing to A[7] -> A(7) reflecting your advice, the same error occurred. Is there any other way?? I would appreciate it if you could give me an answer.
