I assume I can attach a plot for you here - if the attachment goes through, that's what the output looked like for me for m=1, c=1, k=1 (critically damped, which looks correct) with an initial stretch of 2 and velocity of 4. With that correction, your program seems to work. This forces Freemat to do the multiplication element-by-element instead of a matrix multiplication. after the first expression, like so: x=A*exp(-z*w*t.)*sin(wd*t+phi). MathCAD has been extremely frustrating, as I. To do an element-wise multiplication, which is what I assume you want, simply put a. Hey Everyone, I am having a bit of trouble producing a graph for the Graphing Transfer Function thread. This results from trying to multiply two matrices whose dimensions don't match up correctly, namely (A*exp(-z*w*t)) and (sin(wd*t+phi)). By default, Freemat uses the shortformat. If you don't, use format short(for 4 places). If you want to see a lot of decimal places (14, to be precise), use the command format long. I think I did not find anything like that here. Freemat uses the formatcommand to show you a different number of decimal points within the Command Window for numeric variables. In matlab ,We have some in-built functions like 'tf', 'bode' for making the above said things. In C:/Users/tj/Desktop/Vibo_amo.m(Vibo_amo) at line 12Įrror: Requested matrix multiplication requires arguments to be conformant. I want to know if there is a possibility to find the transfer function of any system and plot it on a bode plot. If you try to run it as is, you'll come up with the error: for use with the fft and ifft functions, in order to move the frequency 0 to the center of the vector or matrix. Contour plots in 2D and 3D are now supported, along with labels. An unweighted moving average filter is the simplest convolution filter. It is also used in economics to examine gross domestic product, employment or other macroeconomic time series. The console window has been rewritten, and should be more robust and faster. It is often used in technical analysis of financial data, like stock prices, returns or trading volumes. Also, I gave your program a run, you have a debugging error in line 12. The output format for FreeMat is now closer to MATLABs, and can be adjusted using the format command. If you want to do further manipulation, you'll want to run it as a script (i.e.: take the first line out, define your variables inside the script explicitly, then you can source the script or just type its filename at the prompt). The arguments give you the ability to change the variables at will from the command line, but bear in mind that once the function has executed, you will not be left with any of your calculated variables from inside the function. You need to just type the function name with the arguments, like so: Because you specifically named this a function, to which you pass arguments, you can't execute it line-by-line with the source command.
