Do not have a space or a hyphen in the names of your. If you have a space or hyphen, when you matlab e to html MATLAB will give an error message when it tries to execute the first command and won't try to execute any later commands. It ends with the letter el. You probably typed the number 1, matlab e.

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.

We have exp2 as pow2 with one input but we don't have exp

Help Center Help Center. To get a floating-point approximation with the current precision set by digits , use vpa eulergamma. Represent the Euler-Mascheroni constant using eulergamma , which returns the symbolic form eulergamma. Use eulergamma in symbolic calculations. Numerically approximate your result with vpa. Find the double-precision approximation of the Euler-Mascheroni constant using double.

Help Center Help Center. Calculate the exponential of 1, which is Euler's number, e. Input array, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. 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. For more information, see Tall Arrays. This function fully supports thread-based environments. This function fully supports GPU arrays.

You can actually find this in the symbolic toolbox as eulergamma. Toggle Main Navigation. David Goodmanson on 23 Jun They don't want to do so, for good reasons. Accepted Answer. 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 Select a Web Site Choose a web site to get translated content where available and see local events and offers. Me: Why would you call the exponential function bro??? Reload the page to see its updated state. Great feedback Rik.

We also don't always throw the exceptions the IEEE spec suggests, since we have complex numbers available. To plot a surface, you may want to think of the surface as parametrized. Stephen did try it your way, and he found that exp 1 was faster though not by a lot. Support Answers MathWorks. Numerically approximate your result with vpa. Main Content. Me: What did you just say? Based on your location, we recommend that you select:. Therefore if you take the real theoretical then the closest double precision representation of its log is 1 exactly, not the next number after 1 and not the previous number before 1. The tic documentation clearly states: "Sometimes programs run too fast for tic and toc to provide useful data. You have a modified version of this example. Edited: David Goodmanson on 17 Jun As of a few releases ago, sym 'pi' is not the same as sym pi. All variables must have data types that support the calculation.
