fillarray

Maxima Function

Calling Sequence

fillarray (A, B)

Description

Fills array A from B, which is a list or an array.

If a specific type was declared for A when it was created, it can only be filled with elements of that same type; it is an error if an attempt is made to copy an element of a different type.

If the dimensions of the arrays A and B are different, A is filled in row-major order. If there are not enough elements in B the last element is used to fill out the rest of A. If there are too many, the remaining ones are ignored.

fillarray returns its first argument.

Examples:

Create an array of 9 elements and fill it from a list.

(%i1) array (a1, fixnum, 8);
(%o1)                          a1
(%i2) listarray (a1);
(%o2)              [0, 0, 0, 0, 0, 0, 0, 0, 0]
(%i3) fillarray (a1, [1, 2, 3, 4, 5, 6, 7, 8, 9]);
(%o3)                          a1
(%i4) listarray (a1);
(%o4)              [1, 2, 3, 4, 5, 6, 7, 8, 9]

When there are too few elements to fill the array, the last element is repeated. When there are too many elements, the extra elements are ignored.

(%i1) a2 : make_array (fixnum, 8);
(%o1)             {Array:  #(0 0 0 0 0 0 0 0)}
(%i2) fillarray (a2, [1, 2, 3, 4, 5]);
(%o2)             {Array:  #(1 2 3 4 5 5 5 5)}
(%i3) fillarray (a2, [4]);
(%o3)             {Array:  #(4 4 4 4 4 4 4 4)}
(%i4) fillarray (a2, makelist (i, i, 1, 100));
(%o4)             {Array:  #(1 2 3 4 5 6 7 8)}

Multple-dimension arrays are filled in row-major order.

(%i1) a3 : make_array (fixnum, 2, 5);
(%o1)        {Array:  #2A((0 0 0 0 0) (0 0 0 0 0))}
(%i2) fillarray (a3, [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
(%o2)        {Array:  #2A((1 2 3 4 5) (6 7 8 9 10))}
(%i3) a4 : make_array (fixnum, 5, 2);
(%o3)     {Array:  #2A((0 0) (0 0) (0 0) (0 0) (0 0))}
(%i4) fillarray (a4, a3);
(%o4)     {Array:  #2A((1 2) (3 4) (5 6) (7 8) (9 10))}
