MATLAB, like Maple and other mathematical software but in contrast to spreadsheets like Excel, automatically allows and works with complex numbers. All arithmetic with complex numbers works in the usual way. This is because MATLAB is used widely in both mathematics where i is most commonly used for the square root of -1 and electrical Engineering where j is more commonly used for the square root of There are a number of special functions for working with complex numbers. These include creating complex numbers from real and imaginary parts, finding the real or imaginary part, calculating the modulus and the argument of a complex number. These are the constant pi and the square root and exponential functions. Use the format command to display all digits. There are special functions for working with complex numbers and MATLAB's functions can take real or complex arguments. Complex numbers MATLAB, like Maple and other mathematical software but in contrast to spreadsheets like Excel, automatically allows and works with complex numbers. The first argument 3 is the real part, the second argument 2 is the imaginary part. Find the value of e. Find the square root of

And you will find an exp function in everything from a spreadsheet to basic to Fortran to Python, matlab e. But really only the two of them. It runs more slowly, taking 3x as much time!

Exponential values, returned as a scalar, vector, matrix, multidimensional array, table, or timetable. For complex values of X , Y is complex. The data type of Y is the same as that of X. This function fully supports tall arrays.

DGM on 22 Oct The code for viewSolid treats the lower y limit as an inline function of x, and the independent variable in an inline function has to appear explicitly. Lets look up the term natural logarithm : Wikipedia defines it as "The natural logarithm of a number is its logarithm to the base of the mathematical constant e James Tursa on 5 Jul Or you can define 'e' yourself. As precedent, pi isn't a keyword. An Error Occurred Unable to complete the action because of changes made to the page. What is your problem? So defining en as a built-in function in MATLAB would kill the function precedence bias and show the true performance of both codes. All contributions are very much appreciated. So the solution the MathWorks uses is to totally minimize the named constants they provide.

So is there any reason you could imagine to want to define e as a separate variable? Here is why:. And we already have a hugely valuable function named gamma, which computes the gamma function. Walter Roberson on 21 Dec Error using i. Start Hunting! This function fully supports GPU arrays. Minor issues that I thought would be easily fixed. I never said "that log is having to treat binary double precision exp 1 specially to get exactly double precision 1" and I'm not saying it now. For example:. That value is NOT the exact number. Really, there is only one reason why you might want to have e laying around. It computes exp x , and is highly optimized to compute exactly that function to within machine precision.
