The array created by javaArray is equivalent to the array created by the Java code A = new PackageName.ClassName[x1]...[xN]; Examples collapse all Create 4-By-5 Java Array Open Script 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);

Input Arguments collapse all PackageName.ClassName — Name of Java class character vector Name of the Java class, including the package name, specified as a character vector. Data Types: char x1,...,xN — Dimensions of the array integer 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 ObjArr — Java array Java array Java array with dimensions x1,...,xN. More About collapse all Java Array Object A Java array object is an object with Java dimensionality. Tips To create an array of primitive Java types, create an array of the equivalent MATLAB type, shown in the Conversion of MATLAB Types to Java Types table. See Conversion of MATLAB Argument Data.
