两个gpuArray double 数据相乘 提示错误 MATLAB 1、matlab中的乘除法 1.数字之间相乘/相除 >> a=3; >> b=4; (1)相乘(*与.*没区别): >> a*b ans = 12 >> a.*b ans = 12 (2)相除(/与./没区别): >> a=3; >> b=4; >> a/b ans = 0.7500 >> a./b(a除以b) ans = 0.7500 >...
哦对,上述这些显存上的数据,类型是gpuArray,如下图whos a agpu的结果 想要让CPU用这些gpuArray的时候,用gather可以把它们取回到内存变成double(此处不要问问题,不要多想,我假装啥也不知道,用到时候查查文档或者google一下就可能解决的,相信我~) 继续 然后就是是学**怎么用这些gpuArray类型的数据,学**下图中的R...
Without GPU on my computer I have around 1 minute calculation time. But with GPU unfortunately I got an error ""The following error occurred converting from gpuArray to double: Conversion to double from gpuArray is not possible". What is the problem...
用filterDesign设计一个101阶FIR滤波器,导出其滤波器系数为num,num为1个101*1的double数组。注意,不要导出为filter object,filter函数用于gpuArray时,不支持filter object,只能用滤波器系数。 %% 用CPU进行计算A=randn(1e8,1,'single');f=@()filter(num,1,A);timeit(f)% 用时0.5472秒%% 用GPU进行计算A_...

gpuB = gpuArray(b); c = gpuA * gpuB; s = svd(c);end% 执行下面的指令,可以统计运算所耗时间(与CPU上不同,用GPU做计算要用wait):dev=gpuDevice();tim=tic();largeMatrixTest;wait(dev);gpuTime=toc(tim); 尽管多出了两个内存搬运的操作,利用NVIDIA GeForce GTX...

Although the MEX generation was successful when I specify the inputgas a double array (non-gpuArray), it was not successful when I specify it as a double gpuArray. The build was successful but the compilation seems to have failed. The buildLog is like below: ...
