symbolic toolbox find y intercept in matlab

To find the y-intercept of a symbolic expression in Matlab, you can use the "subs" function along with "solve" function from the Symbolic Toolbox. Here's how you can do it:

main.m
syms x y    % Define symbolic variables

% Define the symbolic expression
expr = 3*x + 2*y == 10;

% Find the value of y when x = 0
y_int = solve(subs(expr,x,0),y); 

% Display the y-intercept
disp(['The y-intercept is: ', char(y_int)])
237 chars
11 lines

In this example, the y-intercept of the line represented by the expression 3*x + 2*y = 10 is calculated by setting x to 0 and solving for y using the "solve" function. The resulting value of y is then displayed using the "disp" function.
