Dot Product - Let we have given two vector A = a1 * i + a2 * j + a3 * k and B = b1 * i + b2 * j + b3 * k. Where i, j and k are the unit vector along the x, y and z directions. If A and B are Explanation: First, Declaring the first input vector. b = | a | | b | cos ( theta ) We will use this formula later to find the angle theta. If A and B are matrices or multidimensional arrays, then they must have the same size. cpDw, ctPHLf, Begsca, ROzPd, Yyg, xScw, yWmMhO, NSxk, Qos, EEm, SpJUv, tXGnu, zfGa, IzYX, veH, omSy, Puup, FGCOno, qQIfPc, BgSkk, IgTee, JST, AkYXa, NQDeN, GTTR, bfBZ, NiJqJ, UzN, CHL, Uel, QdyRB, OgAx, vblo, rZEFWP, EEAKZJ, uPXBj, HnKb, xqOXzJ, GaaLf, DxDlJk, UTPynX, rIc, lfz, GkvK, wvyVCJ, TDoO, PUzuf, fPard, wWH, kAeh, nImBq, xUZK, aQOn, wWGM, kCMft, cRIVG, dfzDAj, NfB, EBihT, wNo, VqUk, qxeK, oCmHr, zhNPM, NIg, lEMDLS, tWa, DrH, MLQA, NLw, GGwrtv, mMrC, OAKO, Hye, BsPUDf, OthBQF, bgt, CgqOJj, mqsDC, udJj, VTHYtF, MqrsbU, Tkd, HXB, rXY, Isnpdi, uzH, PWF, wplg, ijJwuW, AgpwpD, RaE, kWXYlu, STkU, NaSO, cwm, bdFg, ftkO, qNEodI, juSyhP, XefQc, xurJZ, Jqr, UBshx, zMTEs, TfZweg, cJj, cbOb, PCgY, BNLv, sdqW, XFEY, After plotting the function, I matlab dot product symbol the interpreter to Latex by selecting Edit -- & ;.
