How do matlab calculations work? In particular, how does it work with matrices? Can anyone explain, or give links to the rele ... gorithm, or perhaps my class is not optimized that much. Matlab also performs all other operations with matrices much faster.

Matlab doesn't want to count the integral, everything is fine with the integral itself, but in response it just outputs the unread integral( Can we do something about it, or will we have to accept it?

Tell me, please, how in Matlab to decompose a function into a Taylor series of two variables?

I solved a system of equations using the built-in method, but in the end I got only one point, instead of three. How do I fi ... 3.72*x(1)^5)+x(2); F(2) = 0.2*(-x(1)-1.5*x(2)+1.2); end And the script itself fun = @root2d; x0 = [0,0]; x = fsolve(fun,x0)

Hello, please tell me. I created the matrix b=250:-50:50 a=linspace(-27,53,5) w=[a;b] And now I need to output it using fpr ... ', w) But this way the title is displayed in both the first and second lines. How do I make it shared? Thank you in advance.

Here is the code but I need to have colored lines on the graph how do I do this? explot ('2*x^3 - 3*x^2 + 5', [-5 5]) hold on explot ('x^3/(x^2-1)', [0 3]) axis tight

How can I implement filtering of a noisy real signal using only code? When working with harmonic signals, everything is simpl ... (3),plot(t,y), title("Выходная последовательность после оптимальной фильтрации"); It must be converted to an audible signal.

Please tell me about the Fourier transform in the MATLAB environment. The 3rd day I try to understand through Google and peri ... e(-fs/2,fs/2,length(x)); area(f,abs(sfx)); title('Амплитудный спектр сигнала'); xlabel('Частота(Гц)'); ylabel('Амплитуда');

I am creating an MxN array, need to select multiple columns from the end of the array, i.e. multiple columns with numbers N, N-1, N-2...N-K, in Matlab. A search of the documentation yielded nothing.

You need to write the necessary code instead of comments. I'm not strong in Matlab, can someone help?) function JacobiRo ... ); k=k+1; endwhile k Lamda=A; endfunction function s=sign(x) if x<0 s=-1; else s=1; endif endfunction

I have the following code in Matlab: fileID = fopen('input.txt','r'); formatSpec = '%f'; y = fscanf(fileID,formatSpec); ste ... exp(x/b)+x^2/3+x' ? Or advise any other a numerical method for finding the coefficients of the resulting nonlinear function.

You need to specify a vector consisting of functions, for example: g = @(x, y) x.^2 + y.^2; f = @(x, y) x.^3 + y.^4; It i ... the vector. So that you can specify a vector of functions as a parameter in a custom function. How to write this in Matlab?
