How can I cast 4 octets in 32bit signed integer type ?

Hi,

How can I cast a suite of 4 octet/char to obtain an 32 bit signed integer (sint32).

For instance [198 90 72 0] => -967161856 (and not [phone]).

An equivalent operator to "y = &(type *)&x" in C or to "cast" in LabVIEW.

Thanks,

Benjamin

typecast(uint8([1 2 3 4]),'int32')

Thanks for your answer, it works but before it needs to swap the octets :

data =  [198 90 72 0];

signed_integer_32 = typecast(uint8(data(end:-1:1)),'int32')
