MATLAB: By which command a figure of 3 parametrs can be obtain

MATLAB

I have 3 parameters.time,height and temperature.I want to get a 2D figure having time on x-axis height on y-axis and temperature in between x and y axis.noted that in my case Temperature depends on time and height.

Best Answer

Depending on what form your data takes:

plot3(time, height, temperature)

or possibly

surf(time, height, temperature, 'edgecolor', 'none')

or possibly

F = TriScatteredInterp(time, height, temperature);
[X,Y] = ndgrid(time, height);
Z = F(X,Y);
surf(X, Y, Z, 'edgecolor', 'none')

MATLAB: Surf plot using meshgrid

Try this :

snr_data = xlsread('snr values.xlsx');
depth = [1,2,3,5];
level = 1:7;
depth_mesh = meshgrid(depth,level).';
level_mesh = meshgrid(level,depth);
surf(depth_mesh,level_mesh,snr_data)

I hope it helps !

MATLAB: How to fit experimental data on only one ordinary differential equations (out of multiple equations) with multiple unknown parametrs

Definitely possible! The easiest way to describe this is to quote Monod kinetics and curve fitting.

The strategy is to put your differential equation and the ODE solver call inside the objective function you want to fit. It integrates the equations with the parameters passed to it, and returns the solved equation as the output of the objective functions. You can specify that c(4) and c(5) are known inside the objective function file, and only fit c(1)...c(3). Specify the initial conditions inside the objective function, or you can also fit them as parameters if you wish. (I’ve done all those.)

With a vector output, you can use nlinfit, lsqcurvefit, or with an extra step, fminsearch to do the fit.
