write an equation with graph
显示 更早的评论
Hello, I need help with writing an equation that has 3 parameters in Matlab and plot the graph of it.
The equation is : Rb= SF * CR* BW/2^SF (bit/sec)
the x-axis is for time and the y-axis is for bits
I want to change the values of 2 parameters and make one stable and see the difference.
any help please ??

Hi Diana,
Can you inclde what the values of SF, CR, BW are? It would be easy to share what you have tried so far and where did you struck? What are the inputs and expected outputs?
Regards,
Sriram

This might help you:
SF = [7,8,9,10,11,12];
CR = [1,2,3,4];
BW = [125,250,500];
BW_fixed = BW(1); % fixed Bandwidth
[X_SF,Y_CR] = meshgrid(SF,CR);
Rb= X_SF.*Y_CR.* BW_fixed./2.^X_SF;
surf(X_SF,Y_CR,Rb)
