Convert given decimal number to binary number.
Example x=10, then answer must be 1010.
whereas str2double(dec2bin(x) succeeds, I dont agree it is correct.
str2double(dec2bin(10)) -> 1010
str2double(dec2bin(10)) + 2 -> 1012 ;
this makes little sense in decimal nor in binary code.
I suggest correcting the check to y_correct ='1010'
Why doesn't the built in function dec2bin() work here?
dec2bin returns a character vector, the answer must be an int type
Inner product of two vectors
Sum of first n terms of a harmonic progression
Getting the indices from a vector
Make roundn function
Compute LOG(1+X) in natural log
Add two different item as shown in example
Check that number is whole number
Find the rank of a matrix
