Create Copy of Java Array
To make a copy of an existing Java® array, use subscript indexing. For example, create and initialize
origArray
.
origArray = javaArray('java.lang.Double',3,4); for m = 1:3 for n = 1:4 origArray(m,n) = java.lang.Double((m*10)+n); end end origArray
origArray = java.lang.Double[][]: [11] [12] [13] [14] [21] [22] [23] [24] [31] [32] [33] [34]
Copy the entire contents to newArray
.
newArray = origArray(:,:)
newArray = java.lang.Double[][]: [11] [12] [13] [14] [21] [22] [23] [24] [31] [32] [33] [34]
Change elements of newArray
.
newArray(3,:) = java.lang.Double(0)
newArray = java.lang.Double[][]: [11] [12] [13] [14] [21] [22] [23] [24] [ 0] [ 0] [ 0] [ 0]
The values in origArray
do not change.

origArray = java.lang.Double[][]: [11] [12] [13] [14] [21] [22] [23] [24] [31] [32] [33] [34]
