Comprehensive Mathematics for Computer Scientists

  This two-volume textbook accomplished arithmetic for the operating machine Scientist is a self-contained entire presentation of arithmetic together with units, numbers, graphs, algebra, common sense, grammars, machines, linear geometry, calculus, ODEs, and exact issues akin to neural networks, Fourier concept, wavelets, numerical matters, statistics, different types, and manifolds.

Algebraic Semantics of Imperative Programs

Algebraic Semantics of crucial courses offers a self-contained and novel "executable" advent to formal reasoning approximately principal courses. The authors' fundamental target is to enhance programming skill by means of enhancing instinct approximately what courses suggest and the way they run. The semantics of valuable courses is laid out in a proper, carried out notation, the language OBJ; this makes the semantics hugely rigorous but easy, and offers aid for the mechanical verification of application houses.

Structured Matrices in Mathematics, Computer Science, and Engineering II

Many vital difficulties in technologies, arithmetic, and engineering should be diminished to matrix difficulties. furthermore, numerous purposes frequently introduce a distinct constitution into the corresponding matrices, in order that their entries should be defined through a undeniable compact formulation. vintage examples contain Toeplitz matrices, Hankel matrices, Vandermonde matrices, Cauchy matrices, decide matrices, Bezoutians, controllability and observability matrices, and others.

Sample text

Select the Average option to get :AVERAGE(A2:A7). Commit the formula and move it to D3. The active cell need not be directly below (or to the right) of the values to use theAutoSum tool. We will get the Count formula into D4 in one step. (f) With D4 as the active cell, open the AutoSum dialog and select Count Numbers. The ant track will be around D2:D3 as these are the closest numbers to the active cell. Use the mouse to select A2:A7 and note how the ant track moves and the formula changes to :COUNT(A2:A7).

Error if the number of columns ofAisnotequal to the number of rows ofB, or when any cells contain nonnumerical values. If you happen to forget to use! -J I, and #VALUEl errors if you forget the [0. Shift ]. (c) Click on G4 and note what the formula bar displays: {=MMULT(A4:BS,D4:ES)}. Your formula has been enclosed within braces {} by Excel. This is a "trademark" of array functions. (d) With G4 still selected, try to delete it with the [D81~tel key. You get a message stating that you cannot change just one cell in an array formula.

N (c) CellASwill now con tain the form ula : SUM(A2:A7) and there will be a mobile dotted line (the ant track) around the range A2:A7. Commit the formula. 1 A little experiment: Replace the 1 in A2 with the word CAT. What happens to the formulas? They just ignore that value and work with th e remaining numbers. But :A2+A3+A4 will give a #VALUE! error. Note how the AutoSum tool was successful in finding the correct range of addends (numbers to be added). Frequently, the sum value is needed at the bottom of the column, but for this exercise we shall move it.
