Here it's an easy problem we try to find the relation between the two functions "dec2bin" & "dec2binvec", so here you must write a function using "dec2bin" to find the result of "dec2binvec".
DEC2BINVEC Convert decimal number to a binary vector.
DEC2BINVEC(D) returns the binary representation of D as a binary vector. The least significant bit is represented by the first column. D must be a non-negative integer.
DEC2BINVEC(D,N) produces a binary representation with at least N bits.
Example: dec2binvec(23) returns [1 1 1 0 1]
