The exp function is an elementary function that operates element wise on arrays.

What does exp mean in matlab.

If a is a vector then mean a returns the mean of the elements. It is used to create vectors subscript arrays and specify for iterations. In mathematics the abbreviation exp stands for the word exponent. The parameter μ is also equal to the standard deviation of the exponential distribution.

Y exp x returns the exponential for each element of x for complex it returns the complex exponential. The data type of y is the same as that of x. Exponential values returned as a scalar vector matrix or multidimensional array. Its domain includes complex numbers.

The data type of y is the same as that of x. If you want to create a row vector containing integers from 1 to 10 you write. 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 matrix then mean a returns a row vector containing the mean of each column.

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. Use expm for matrix exponentials. This dimension becomes 1 while the sizes of all other dimensions remain the same. 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.

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. 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. The standard exponential distribution has μ 1. What does exp mean in math.

Expm log log10 expint. The colon is one of the most useful operator in matlab. The expression 5 exp 2 for example means 5 raised to the second power. An exponent is a number placed after another number to indicate the power to which the former number is to be raised.

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.
