function ret = Int2Hex(var) Prints integer array to hexadecimal string varType = class(var) cast signness away: if ( u ~= varType(1) ) varType = [ u varType] var = typecast(var,varType) end nBits = str2double(varType(5:end)) if (64 == nBits) split 64 bit case into two 32 s cuz dec2hex doesn t handle 64 bit... varType(5:end) = 32 var = typecast(var,varType) end ret = dec2hex(var) if (64 == nBits) littleEndian = all(typecast(uint32(1), uint16 )==[1 0]) first = 1 + littleEndian second = 2 - littleEndian ret = [ret(first:2:end,:),ret(second:2:end,:)] end end

抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定.(parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)
