In general, imag cannot extract the entire imaginary parts from symbolic expressions containing variables. However, imag can rewrite and sometimes simplify the input expression:. If you assign numeric values to these variables or if you specify that these variables are real, imag can extract the imaginary part of the expression:.

Complex numbers were introduced by the Italian famous gambler and mathematician Gerolamo Cardano in while he found the explicit formula for all three roots of a cube equation. Many mathematicians contributed to the full development of complex numbers. The rules for addition, subtraction, multiplication, and division of complex numbers were developed by the Italian mathematician Rafael Bombelli baptized on 20 January ; died The notations 1 and i for unit vectors in horizontal positive direction and vertical positive direction, respectively, were introduced by Leonhard Euler who visualized complex numbers as points with rectangular coordinates, but did not give a satisfactory foundation for complex numbers theory. He also suggested to drop the unit vector 1 in presenting vectors on the plane.

This means that you can take powers and roots of any number. For the roots: either use a polynomial for which you know the roots, or find the roots in advance, by using your own Newton solver. How long does it take your code to make a by plot that is, a plot in which both the x- and y-axes have points?

This applies to functions operating on gpuArray objects directly and to functions operating on gpuArray data using arrayfun. If using arrayfun , the function input can be specified as complex within the arrayfun call. Release Rb. If the output of a function running on a GPU could potentially be complex, you must explicitly specify its input arguments as complex using the complex function. Search MathWorks. Trial software.

Notice that it is possible to have real and complex numbers in the same array, since both are of class double.

Find the imaginary parts of these numbers. What is weird is that when I run the script below, it doesn't return complex numbers:. The function is set up this way so that you can use this as part of a conditional, so that a block only is executed if all elements of array A are real.

The latest reviewed version was checked on 7 August Note 2: Since i is used as the complex number indicator it is not recommended to use it as a variable, since it will assume i is a variable.
