MATLAB: Passing values to Bash script

linuxscript

Let's say I have a matlab file that calculates some values, giving:

alpha = 7
beta = 9

Now, I want to pass these values to a Bash script for use.

What is the syntax for doing this?

Best Answer

Example:

cmd = sprintf('alpha=%d beta=%d ls | head -$beta | tail -$alpha', alpha, beta);
system(cmd)

MATLAB: How to introduce symbolic variables as input in a script

Run the following. It is exactly what you want:

iteration = 0;
T0n = eye(4);
links = input ('Introduce number of links ');
while iteration<links
        iteration=iteration+1;
        teta=sym(input('teta value\n','s'));
        a=sym(input('a value\n','s'));
        d=sym(input('d value\n','s'));
        alpha=input('alpha value ');
          A=[cos(teta), -cos(alpha)*sin(teta), sin(alpha)*sin(teta), a*cos(teta);
             sin(teta), cos(alpha)*cos(teta), -sin(alpha)*cos(teta), a*sin(teta);
             0,         sin(alpha),           cos(alpha),            d;
             0,         0,                    0,                     1];
         T0n=T0n*A
   end

MATLAB: How to plot this implicit function

Try symbolic expression

clc,clear
alpha=1.5; A=0.0207; gamma=0.25;
syms beta eps
x = (beta-alpha*(beta-gamma)+sqrt((beta-alpha*(beta-gamma)).^2+4*alpha*beta*gamma*A))./(2*beta);
y =  x.*(1-x).*beta/gamma;
t =  -x+x.*y.*(alpha-eps*beta)./((A+x+y).^2);
d =  eps*beta.*x.*y.*(x.^2+(A+x).*x+A*alpha)./((A+x+y).^3);
    % convert symbolic expression to function handle
F = matlabFunction(t.^2 - d,'vars',[beta eps]);
ezplot(F,[0,1,0,1]);
