Do not have a space or a hyphen in the names of your. If you have a space or hyphen, when you publish 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. The solve command takes as its input a symbolic expression, not an equation and assumes that the expression is equal to 0. To solve the equation, give the command:. Give the command before giving the command for the plot you want to appear in the new window. The first thing is to try is the command hold off before the new plot command. To plot a surface, you may want to think of the surface as parametrized. Since it is two dimensional, there will be two parameters. For example, for the ellipsoid I can use with.

Be careful to make it as accurate as possible, but that is your problem entirely. John D'Errico on 13 Nov

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.

Help Center Help Center. This topic shows how to compute matrix powers and exponentials using a variety of methods. For example:. The results using fractional powers depend on the distribution of the eigenvalues of the matrix. For example, to square each element in a matrix you can use A. The sqrt function is a convenient way to calculate the square root of each element in a matrix. An alternate way to do this is A.

David Goodmanson on 23 Jun Yes but i still cannot put log base e. In fact, this is a commonly provided function in almost every computer language you will ever learn. If you still refer to it as 'silly computation', you should re-read the paragraphs below. I'm not sure of the totality of what you're tyring to illusrate. Open Mobile Search. 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. In double-precision floating-point systems, this is typically the case. MATLAB: They say sir that this is for your security plus there are no applications for that number sir, so why should they care? Delonte Goodman on 13 Nov If your next post is that childish again, I will be out. David Goodmanson on 27 Jun For example, in electrical engineering and control systems engineering , the imaginary unit is normally denoted by j instead of i , because i is commonly used to denote electric current. Note that when I want the true mathematical constant, I can still use sym like this:. Off-Canvas Navigation Menu Toggle.

Your detailed answer, the time you took to write it, and the effort you made to explain and code examples to support your viewpoint is very much appreciated. You know Minor issues that I thought would be easily fixed. To get a floating-point approximation with the current precision set by digits , use vpa eulergamma. You start by creating a grid of points the parameter values which will be used for plotting. Trial software. Just use the function exp, as people all around the world have happily done for many years. The number of bug reports they would get? Paul on 28 May I just finished an online course on Python recently and I found it to be very useful. I use gamma a LOT as a function. Elapsed time is 6. Calling a constant value with a stored value is logically and truly faster than calling a function that involves calculations. Vote 1. Even Euler himself, if resurrected again, would fail to find a single application for that number sir.
