Exp In Mat

The data type of y is the same as that of x.

Exp in mat.

. In other words exp x e x. The exp stands for exponential. The expression 5 exp 2 for example means 5 raised to the second power or 5 x 5.

In mathematics the abbreviation exp stands for the word exponent. The real exponential function. Can be characterized in a variety of equivalent ways. It s used when it is to much trouble or too expensive to add superscript on top of superscript.

An exponent is a number placed after another number to indicate the power to which the former number is to be raised. Exponential function in mathematics a relation of the form y a x with the independent variable x ranging over the entire real number line as the exponent of a positive number a probably the most important of the exponential functions is y e x sometimes written y exp x in which e 2 7182818 is the base of the natural system of logarithms ln. 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. Since the radius of convergence of this power series is infinite this definition is in fact applicable to all complex numbers see complex plane for the extension of to the complex plane.

The example you give would have a fraction in the exponent. It goes on forever but you don t need to know the value your calculator probably has exp x or e x as a function if as i am assuming it is a scientific calculator. The term exp x is the same as writing e x or e x or e to the x or e to the power of x. Exponential values returned as a scalar vector matrix or multidimensional array.

In this context e is a universal constant e 2 718281828.
