Float to binary string and vice-versa

Hello,
I would like to have following 2 functions written in Matlab (here the C-code):
void getMemoryFromFloat(float floatNumber,char memory[4])
{ // floatNumber is input, memory is output
memory[0]=((char*)&floatNumber)[0];
memory[1]=((char*)&floatNumber)[1];
memory[2]=((char*)&floatNumber)[2];
memory[3]=((char*)&floatNumber)[3];
}
float getFloatFromMemory(char memory[4])
{ // memory is input
return(((float*)memory)[0]);
}
Anyone can give me a hint? To give a quick background, I basically communicate with a C-library that sends me float data that is coded in a string. In a similar way, that library only accepts float data coded in a string.
Thanks!

If you are working with very large variables and/or doing this many times in a loop, you might consider this FEX submission "typecastx" that returns a shared data copy of the input. It is faster and more efficient than the built-in typecast function which returns a deep data copy.
