What is fix function Matlab?

Y = fix( X ) rounds each element of X to the nearest integer toward zero. This operation effectively truncates the numbers in X to integers by removing the decimal portion of each number: For positive numbers, the behavior of fix is the same as floor . For negative numbers, the behavior of fix is the same as ceil .

How are octal numbers formatted in MATLAB sprintf?

The formatSpec parameter must be constant. In formatSpec, hexadecimal numbers must be in the range [0 7F] and octal numbers must be in the range [0 177]. If all the input arrays are constant, the code generator evaluates the sprintf call in MATLAB at compile time.
