Linear algebra sparse arrays sparsearray data format

教學共 2 個步驟，在同一個工作階段中依序執行。每一步都在引擎上實際執行過，下方的輸出就是它產生的結果。

步驟 1

sp = SparseArray[{{1, 1} -> a11, {1, 3} -> a13, {2, 1} -> a21,
	{2, 4} -> a24, {3, 2} -> a32, {3, 3} -> a33}, {3, 4}];
sp//MatrixForm

輸出

MatrixForm[SparseArray[Automatic, {3, 4}, 0, {1, {{0, 2, 4, 6}, {{1}, {3}, {1}, {4}, {2}, {3}}}, {a11, a13, a21, a24, a32, a33}}]]

步驟 2

sp//InputForm

輸出

InputForm[SparseArray[Automatic, {3, 4}, 0, {1, {{0, 2, 4, 6}, {{1}, {3}, {1}, {4}, {2}, {3}}}, {a11, a13, a21, a24, a32, a33}}]]
