Hi everyone

I have an integrator block, and I want to invert its inputs, so I explain

the first input is x the signal to be integrated (the top input)

the second input is y the initial condition (the bottom input)

I want that x became the bottom input and y the top input

thanks in advance

for example the cross product block you have two inputs A & B and one output C C = AxB the question is

how to put the A letter in the place of B input ...

A in the Top and B in the bottom of the block

after the inversion of the inputs

B in the Top and A in the bottom of the block

without affectiong the output

Does this need to be done based on a condition that is set during simulation?

See the image below. A variable switches the input on the switch blocks - see switch for information on setting the input conditions. In this figure the input is switched by a constant but you could replace that to suit your needs (a signal generator for example).

So in this example whilst the switch variable is not greater than 0, input 1 is A, and 2 is B. When it is, these swap, A becoming the input to 2, and B becoming the input to 1.
