Not-a-number is generated by trying to evaluate expressions like 0/0 or Inf-Inf that do not have well defined mathematical values. Infinity is generated by dividing a nonzero value by zero, or by evaluating well defined mathematical expressions that overflow, i.e., exceed realmax. Several special functions provide values of useful constants. For other functions, you can see the code and even modify it if you want. For example, for built-in functions, you cannot see the code. There are some differences between built-in functions and other functions. Other functions, like gamma and sinh, are implemented in M-files. Built-in functions are part of the MATLAB core so they are very efficient, but the computational details are not readily accessible.
Some of the functions, like sqrt and sin, are built in. For a list of the elementary mathematical functions, typeįor a list of more advanced mathematical and matrix functions, type Most of these functions accept complex arguments.
MATLAB also provides many more advanced mathematical functions, including Bessel and gamma functions. Taking the square root or logarithm of a negative number is not an error the appropriate complex result is produced automatically. Jc = findobjinternal( hfig, '-isa ', ' provides a large number of standard elementary mathematical functions, including abs, sqrt, exp, and sin.
