Copy CodeCopy Command 可以使用傅里叶变换来分析数据中的变化,例如一个时间段内的自然事件。 天文学家使用苏黎世太阳黑子相对数将几乎 300 年的太阳黑子的数量和大小制成表格。对大约 1700 至 2000 年间的苏黎世数绘图。 loadsunspot.datyear = sunspot(:,1); relNums = sunspot(:,2); plot(year,relNums) ...
FFT和Matlab中操作FFT FFT(离散傅氏变换的快速算法),FFT(Fast Fourier Transformation)是离散傅氏变换(DFT)的快速算法。即快速傅氏变换。 输入N+1个数,输出N+1个数;意义不同...采样周期) 则变换后的N+1个数对应的x轴变为频率,范围为0~fs,以fs/N为间隔,即为频率点{0,fs/N,2*fs/N,……,fs}, m...

当我按照说明做matlab仿真时,在command界面中输入:fft_tb时跳出了如下错误 说是这个文件没存在,让我进行HDL级仿真,但我已经进行RTL级仿真了,不知道怎么回事了。。。 但是进行modelsim仿真还是没有错误的,还长了些见识。 (1)On theProcessingmenu, point toStartand clickStart Analysis & Elaboration 查找了Q2...
Once you save the above in a*.m file. You can run the following example from the command line: % Define Sampling information Theta_Inc = 2*pi/360; N_Theta = 360; Theta_Range = linspace(-180,180,N_Theta+1)*Theta_Inc; Theta_Range = Theta_Range(1:N_Theta); ...
Then I make 'Run -all' command and wait for result. However, in spite of there is a $finish task in the testbench, simulation never stops. If I make forced stop of simulation, I see signals source_valid, source_real, source_imag being in a HiZ state all the way. T...
This is my code: I'm trying to get my bot to respond depending on the python I enter with the t.say command. E.g. t.say print('hello') would result in the bot returning Hello. However, I'm running int... Why is iCustom() returning default empty value (2147483647) for my indi...
