How to type the root number two in matlab

The root number in matlab is represented by ^, and the expression method of the root number two is: 2 ^0.5 .

If you just want to find the value of root two, you can use the sqrt function: sqrt(2).

Note:

In matlab, the cubic root of a number can be expressed as a^(n). For example, if you want to express 2 under the 3rd root , can be written as 2^(1/3).

B = sqrt(X) returns the square root of each element of the array X. For negative or complex elements of X , sqrt(X) produces a complex result.

The domain of the sqrt function includes negative numbers and complex numbers. For negative complex numbers z = u i*w, the complex square root sqrt(z) returns sqrt(r)*(cos(phi/2) 1i*sin(phi /2)), where r = abs(z) is the radius and phi = angle(z) is the phase angle in the closed interval -pi

If you want negative and complex numbers to return an error message instead of returning a complex result, use realsqrt instead.
