Create 4-by-5 array of java.lang.Double type. 

x1 = 4;
x2 = 5;
dblArray = javaArray('java.lang.Double',x1,x2);

Fill in values. 

for m = 1:x1
    for n = 1:x2
        dblArray(m,n) = java.lang.Double((m*10) + n);
    end
end

Display results.

  java.lang.Double[][]:

    [11]    [12]    [13]    [14]    [15]

Input Arguments

collapse all

Name of the Java class, including the package name, specified as a string or character vector.

Data Types: char

Dimensions of the array, specified as an integer. If any argument is zero, javaArray creates a zero-length Java array with the specified number of dimensions. A zero-length Java array is not the same as an empty MATLAB® array, which is converted to a Java null when passed to a Java method.

Data Types: double

Output Arguments

collapse all

Java array with dimensions x1,...,xN.
