There is a direct command in matlab for images subtraction i.e. I = imread('rice.tif'); Iq = imsubtract(I,50); subplot(1,2,1), imshow(I) subplot(1,2,2), imshow(Iq) You can use any weighing factor with that. Regards Robin
hi! Why is that when I ran a program in matlab with findtheta command an error is dispalyed that undefine command/function 'findtheta'. thanks!
Hi guys I am trying to compute the transfer function for block diagrams in series and parallel USING matlab and I will like to know how to use the parallel and series function/command. thanks
hi first you need to define n , as a matrix n= 1 : 1 :128 ; and then write down the equations and then if you want to plot the two signals in the same graph you use: graph subplot(3,1,1); plot(x1) title('...............'); subplot(3,1,2); plot(x2) title('.......................'); that for example how to use multi
hello i use subs command in my matlab programm: i want to get F in numerical mode,F obtained from integral of f1/f2 in x variable F=int(f1/f2,x); I defined all the parameters like f1 and f2 in matlab program but when i use subs command for getting F in numerical mode : F=subs(F) it gives me: (...)
Hi all im currently trying to design a guitar tuner in matlab and am new to this. Currently I record my string using the following code then bandpass filter it and then FFT it.

Hi everyone, I'm currently writing a matlab problem that has one of this command line x^4+c3*x^3+c2*x^2+c1*x+c0=0. My aim is to come up with the values of x. All the c3,c2,c1,c0 parameters have been properly defined. However it keeps showing the Error File that the assignment statements cannot produce a result. Could I ask why is this so?
you can use subplot(N,1,n), plot(...), xlabel(' '), ylabel(' '), title(' ') for each

hi, pretty easy code. there are functions in matlab. the "find" function along with "max" and "min" can be employed to get what u desire for. even find is not necessary unless u want to get the index of those values.. suppose ur matrix is a = magic(5); then max(a) will list out 5 values, with each value the max of the columns of "a". c
I do have a S(f) calculated and now I made a x-y coordinate system using this code subplot(2,2,1); semilogx(f,real(S11)); xlabel('Frequency'); ylabel('Real(S11)'); title('Real(S11) = Real(S22)'); grid; As a figure I get empty drawing so i'm interested how to plot the line for the S that i have calculated.What is the co
hi, if i understand you rigth, you want to zero pad a matrix, rigth. well usaly you do it in order to do soom calc on it, and most of the matlab function do contain another argomant that tells them to zeropad it's inputs before using it. so you should chack with the help XX about whtere your function has this, and any way here's a code that doe

In matlab, there are two functions that can represent convolution function. one is CONV, the other is FILTER. But, their output point numbers are different. As bellowing example, stp_rep2 is twice times length than stp_rep3. Which one is more reasonable? stp_rep1=filter(b,a,x_imp); stp_rep2=conv(x_in,stp_rep1); stp_rep3=filter(b,a,x_in);
