parfor loopvar = initval:endval; statements; end executes a series of MATLAB® statements for values of loopvar between initval and endval, inclusive, which specify a vector of increasing integer values. The loop runs in parallel when you have Parallel Computing Toolbox™ or when you crea...
loopVar,initVal,endVal与for循环一样的。 endVal 可以理解为把整个任务分为几个部分去运行,endVal 可以大于电脑的核数或者说worker。 所以这个函数并没有说明是怎么拆分数据的。 官方的说法:Loop iterations are executed in parallel in a nondeterministic order. 可以理解为随机拆分执行吗? 关于第三个问题:怎么...
parfor:parallel for 循环 我们知道,matlab 更适合的处理对象是矩阵,而不是大规模的循环运算。当有时不得不使用 for 循环时,如果提高 for 循环的执行效率呢。这就是 parfor 的用武之地了,既然是并行运算,就是一次可以执行多次 iterations 处理(类似于操作系统的多线程作业),以加快循环的速度。与传统 for 循环最...
for i=1:1024 A(i) = sin(i*2*pi/1024); end plot(A) To interactively run code that contains a parallel loop, you first open a MATLAB pool. This reserves a collection of MATLAB worker sessions to run your loop iterations. The MATLAB pool can consist of MATLAB sessions running on your...

而MATLAB真的就无法处理大数据了嘛?答案肯定时否定的。MATLAB很早就有了并行计算工具箱(Parallel Computing Toolbox)来帮助使用者处理大数据,只不过2W以上的数据处理起来就有些差强人意了。下面我们就来介绍MATLAB中处理大数据的两种方法,或者可以说是两个函数。
Is it possible speed up the usual "for" loop in matlab code using "parfor" feature in "parallel processing toolkit" and a GPU system("Nvidia Tesla GPU C2050")? That is, can you create and deploy multiple matlab workers in GPU system just like in a machine with multiple CPU's?

parfordiffers from a traditionalfor-loop in the following ways: Loop iterations are executed in parallel in a nondeterministic order. This means that you might need to modify your code to useparfor. For more help, seeConvert for-Loops Into parfor-Loops. ...
