Brackets at the start of input in matlab ?? [ x , y ] = ....

Question

Hello,

I would like to know what is the use of having inputs in brackets like this :

[fx, fxx] = differentiate(...) why is fx and fxx in square brackets ?

Another example includes this [y,t,ysd] = step(m)

Please explain !

Thanks

Answer 1

Matlab allows multiple return values. fx and fxx will each be assigned a return value of the function.
