Working with Java Arrays

5-35

for m = 1:4

for n = 1:5

dblArray(m,n) = java.lang.Double((m*10) + n);

end

dblArray

dblArray =

java.lang.Double[][]:

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

[21] [22] [23] [24] [25]

[31] [32] [33] [34] [35]

[41] [42] [43] [44] [45]

Another Way to Create a Java Array

You can also create an array of Java objects using syntax that is more typical

to MATLAB. For example, the following syntax creates a 4-by-5 MATLAB

array of type double and assigns zero to each element of the array.

matlabArray(4,5) = 0;

You use similar syntax to create a Java array in MATLAB, except that you

must specify the Java class name. The value being assigned,

0 in this example,

is stored in the final element of the array, javaArray

(4,5). All other elements

of the array receive the empty matrix.

javaArray(4,5) = java.lang.Double(0)

javaArray =

java.lang.Double[][]:

[] [] [] [] []

[] [] [] [] [0]

Note You cannot change the dimensions of an existing Java array as you can

with a MATLAB array. The same restriction exists when working with Java

arrays in the Java language. See the example below.
