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
