y = 0:0.01:5;

t1=0.1; t2=3;t3=5;t4=10;

nu = 5;

u0=1;

figure(1)

hold on

u1 = u0.*erfc(y./2.*sqrt(nu*t1));

u2 = u0.*erfc(y./2.*sqrt(nu*t2));

u3 = u0.*erfc(y./2.*sqrt(nu*t3));

u4 = u0.*erfc(y./2.*sqrt(nu*t4));

plot(y,u1,'-',y,u2,'--',y,u3,'-.',y,u4,':','LineWidth',2)

grid on

xlabel('y');

ylabel('u(y,t)');

legend('t = 0.1','t = 3','t = 5','t = 10','Location','best')

Use -

plot(u1,y,'-',u2,y,'--',u3,y,'-.',u4,y,':','LineWidth',2)

Note the syntax for plotting x and y data using plot is -

plot(x_data, y_data)

在 MATLAB Online 中打开

y = 0:0.01:5;

t1=0.1; t2=3; t3=5; t4=10;

nu = 5;

u0=1;

figure(1)

hold on

u1 = u0.*erfc(y./2.*sqrt(nu*t1));

u2 = u0.*erfc(y./2.*sqrt(nu*t2));

u3 = u0.*erfc(y./2.*sqrt(nu*t3));

u4 = u0.*erfc(y./2.*sqrt(nu*t4));

% Switch the order of u and y in the plot function

plot(u1, y, '-', u2, y, '--', u3, y, '-.', u4, y, ':', 'LineWidth', 2)

grid on

% Update labels accordingly

xlabel('u(y,t)');

ylabel('y');

legend('t = 0.1', 't = 3', 't = 5', 't = 10', 'Location', 'best')
