Section: Type Conversion Functions
y = dcomplex(x)
where x is an n-dimensional numerical array. Conversion follows the general C rules. Note that both NaN and Inf in the real and imaginary parts are both preserved under type conversion.
dcomplex. First, we convert from an integer (the argument is an integer because no decimal is present):
--> dcomplex(200) ans = 2.0000e+02 +0.0000e+00i --> quit
In the next example, a double precision argument is passed in (the presence of a decimal without the f suffix implies double precision).
--> dcomplex(400.0) ans = 4.0000e+02 +0.0000e+00i --> quit
In the next example, a complex argument is passed in.
--> dcomplex(3.0+4.0*i)
ans =
3.0000 + 4.0000i
-->
quit
In the next example, a string argument is passed in. The string argument is converted into an integer array corresponding to the ASCII values of each character.
--> dcomplex('h')
ans =
1.0400e+02 +0.0000e+00i
-->
quit
In the next example, the NaN argument is converted.
--> dcomplex(nan)
ans =
nan + 0.0000i
-->
quit
In the last example, a cell-array is passed in. For cell-arrays and structure arrays, the result is an error.
--> dcomplex({4})
Error: Cannot convert cell-arrays to any other type.
