Use the exponential function exp(y) to compute e^y. For example:
x = 0.2;
Result = (x^2)*exp(4)
Result =

September 19, 2013Why Euler's number e = 2.71828... is not a built-in constant in MATLAB?
3. e in MATLAB stands for 10, so using the code you gave will conflict with the scientific notation e. 4. exp(1) will evaluate the exponential function at x = 1. Why should we evaluate a function at a number x = 1 when we already know its value (Euler's number)? More on researchgate.net

June 19, 202010e5 == 10^5 is not true in MATLAB
If you type in 10e5 == 10^5 ans = logical 0 so 10e5 does NOT mean 10 to the power of 5 but it means 10 to the power of 6. 10e5 == 10^6 ans = logi... More on mathworks.com

November 4, 2017notation - the meaning of "e" in matlab output - Stack Overflow
In matlab, especially when testing a neural network, we see a special type of output. for example, 3.332e-23 or 5.e-235. What is the meaning of "e" in the context of the output? More on stackoverflow.com

My dear Dr. Kareem
you are really great researcher
I don't realize that your point is worthy until i read your complete argument.
Great job, and I hope that they add it.

This is a coding language, not an award ceremony.
you can get euler's number with exp(1);
on the other hand, the number 'pi' can not be calculated directly from an operator like pi(1).
the imaginary number (i) can be written as sqrt(-1); but establishing distinction in the programming language between real and imaginary numbers requires declaring (i).
there are other important numbers which aren't represented at all. i.e. Fibonacci's number. what could be more important than the divine constant?
anyway, create the following matlab scrcipt:
function out=e
out = exp(1);
end
and name the file e.m, and place it in your MATLAB path.
i hope this solves your problem.

It is scientific notation, where e is shorthand for *10^.
You can change the output type in the console using the format command. For example . . .
>> x = 1.123456e5
x =
1.1235e+05
>> format long
>> x
x =
1.123456000000000e+05
>> format longG
>> x
x =
112345.6
>> format hex
>> x
x =

It's scientific notation. AeB denotes A x 10B.

How do i convert scientific notation into number in matlab - MATLAB Answers - MATLAB Central
August 10, 2016 - Although the variable a is indeed stored as a number, when trying to index with it for example MATLAB throws "Warning: Integer operands are required for colon operator when used as index" because it views the scientific notation as a decimal. I believe what Jasmeet was asking is how to make MATLAB understand a value such as 1.0400e+4 as the whole number 10400 that it is, instead of as a non-whole number.

19 hours ago - MATLAB is a weakly typed programming language because types are implicitly converted. It is an inferred typed language because variables can be assigned without declaring their type, except if they are to be treated as symbolic objects, and that their type can change. Values can come from constants, from computation involving values of other variables, or from the output of a function. ... >> x = 17 x = 17 >> x = 'hat' x = hat >> x = [3*4, pi/2] x = 12.0000 1.5708 >> y = 3*sin(x) y = -1.6097 3.0000

How to implement log, ln, and e in MATLAB - Quora
Answer (1 of 2): It is so easy to write the ‘e’, ‘log’, and ‘ln’ in Matlab. We have to know the built-in function defined for the ‘e’, ‘log’, and ‘ln’ variables. The implementation function is, ‘e’ in Matlab is ‘exp()’ ‘log’ in Matlab is ‘log()’ And for ‘ln’ in Matlab is ‘log()’ (In Matlab , l...
