Hello, my model is generally about a mobile charging station where a robot picks up a battery from the charge station and drives it a particular car, charges the car and returns the battery to the station
My stateflow model has an input vector called batLevel (carrying the state of charge for four different batteries) gotten from Simulink using the "vector concatenate" block. I appleid a graphical for loop function (pickBat which has input as batLevel) to check the values of the batLevel vector. If batLevel(i) == 100 then battery i should be disconnected from charge station by setting charge(i) = 0 (charge is a output varriable which indicates if the battery is charging (-1), idle (0), or discharging (1)) and picked up by setting bat(i) = 1 (bat is a data variable which indicates if the robot has pickedup bat(i) or not). charge and bat are both 1xm vectors like batLevel. I called my graphical function before a battery is to be picked up from the charge station and for the other transitions, I used batLevel(i), bat(i) and charge(i) to refer to the active battery. Unfortunately, i get the error "Subscript indices must either be real positive integers or logicals." and batLevel(i) is coloured red.
1) I would like to know if using the for loop is a good option
2) if it is, then why am i having this error and how can I solve it
Attached is a picture of the for loop implementation and the substate where it is called
Thanks in advance for your reply and if further clarification is needed, i will not mind adding some stuff
