What Does Exp Mean In Matlab
An exponent is a number placed after another number to indicate the power to which the former number is to be raised.
What does exp mean in matlab. Exponential values returned as a scalar vector matrix or multidimensional array. Y exp x returns the exponential for each element of x for complex it returns the complex exponential. Exp 227 2 6011e 99 exp 93 2 4512e 40 but if i exp the entire matrix this matrix has inf values. If a is a vector then mean a returns the mean of the elements.
A common alternative parameterization of the exponential distribution is to use λ defined as the mean number of events in an interval as opposed to μ which is the mean wait time for an event to occur. If a is a matrix then mean a returns a row vector containing the mean of each column. Sum sum ii ans 2 how does matlab store the values in the matrix so that operations on individual elements can give a different result than when doing the same operation on the matrix itself. For real values of x in the interval inf inf y is in the interval 0 inf for complex values of x y is complex.
If you want to create a row vector containing integers from 1 to 10 you write. The parameter μ is also equal to the standard deviation of the exponential distribution. The expression 5 exp 2 for example means 5 raised to the second power. Y exp x description.
If a is a multidimensional array then mean a operates along the first array dimension whose size does not equal 1 treating the elements as vectors. By staff writer last updated apr 14 2020 4 20 46 pm et. What does exp mean in math. This dimension becomes 1 while the sizes of all other dimensions remain the same.
The colon is one of the most useful operator in matlab. The data type of y is the same as that of x. Use expm for matrix exponentials. For real values of x in the interval inf inf y is in the interval 0 inf for complex values of x y is complex.
The exp function is an elementary function that operates element wise on arrays. In mathematics the abbreviation exp stands for the word exponent. Expm log log10 expint. It is used to create vectors subscript arrays and specify for iterations.
Its domain includes complex numbers.
