// BIN2dec function
// Given str a binary string, this function returns the decimal number whose the
// binary representation is given by str
//
// -Input :
//    str : a string (or a vector/matrix of strings), containing only characters
//         '1' and '0'
// -Output :
//    y : a scalar/vector/matrix
//
// F.Belahcene

// check the type of input argument
