If a dimension is singleton then it is virtually expanded to the required size (i.e., equivalent to a repmat operation to get it to a conforming size but without the actual data copy). The first two dimensions must conform using the standard matrix multiply rules taking the transa and transb pre-operations into account, and dimensions 3:end must match exactly or be singleton (equal to 1). Which would be equivalent to the MATLAB m-code: i.e., MTIMESX treats these cases as arrays of 2D matrices and performs the operation on the associated parings. The remaining dimensions are duplicated and specify the number of individual matrix multiplies to perform for the result. Mtimesx('SPEEDOMP','OMP_SET_NUM_THREADS(4)') % sets SPEEDOMP mode with number of threads = 4įor nD cases, the first two dimensions specify the matrix multiply involved. 'N' or 'n' = No pre-operation (the default if trans_ is missing)ĭirective = One of the modes listed above, or other directivesĬ = mtimesx(A,B) % performs the calculation C = A * BĬ = mtimesx(A,'T',B) % performs the calculation C = A.' * BĬ = mtimesx(A,B,'g') % performs the calculation C = A * conj(B)Ĭ = mtimesx(A,'c',B,'C') % performs the calculation C = A' * B' Transb = A character indicating a pre-operation on B: Transa = A character indicating a pre-operation on A: Where transa, transb, and directive are the optional inputs:
The general syntax is (arguments in brackets are optional): SPEEDOMP: Fastest BLAS, LOOPS, or LOOPOMP method even if it doesn't match MATLAB exactly SPEED: Fastest BLAS or LOOPS method even if it doesn't match MATLAB exactly MATLAB: Fastest BLAS or LOOPS method that matches MATLAB exactly (default) LOOPSOMP: Always uses OpenMP multi-threaded C loops if available
LOOPS: Always uses C loops if available Can meet or beat MATLAB for speed in most cases Can match MATLAB results exactly or approximately as desired

Utilizes BLAS calls, custom C loop code, or OpenMP multi-threaded C loop code Supports Transpose, Conjugate Transpose, and Conjugate pre-operations It also provides benchmarks, such as the speed of a memory card, an SD card speed test, a flash card read-write test, and SD-card speed or measurement of micro SD performance.
You can test not only SD (secure digital) cards, but also USB flash drives, even hard drives that are connected via USB. Supports multi-dimensional (nD, n>2) arrays directly sdspeed lets you verify the integrity of a flash SD card or USB device.

Nothing more simple! By using our installer you will get access to the Need for Speed 2015 Mac OS X DELUXE Version. If you are here, you want to play this game on your Mac OS X device. Sometimes the SD card won’t mount properly if you insert the card too slowly or too quickly. If your card doesn’t mount If you insert your card and it doesn’t mount, remove the card and insert it again. Developed by Ghost Games and published by Electronic Arts, this game is the twenty-second installment in the long Need for Speed series. Always wake your computer and eject the SD card before removing it from your Mac. Need for Speed is the newest title in the series, and it’s said that it could be an unofficial ”Need for Speed Underground 3”.
