MATLAB: ??? Error using ==> mldivide (out of memory)

Question

ERROR DISPLAYED:

??? Error using ==> mldivide

Out of memory. Type HELP MEMORY for your options.

Error in ==> RocketGamma2 at 75

a = deltav/deltat;

CODE:

yo = [0;0];

[t y] = ode15s('F_Rocket',t,yo);

deltav = diff(y(:,2));

deltat = diff(t);

a = deltav/deltat;

figure;

plot (t(1:nc-1),a); grid on;

xlabel('Tiempo [s]');

ylabel('Aceleracion [m/s^2]');

title('Aceleracion vs. Tiempo');

I'm asking for an alternative way of obtaining the same result, if possible, without having to make memory adjustments.

Thanks, Moya

Answer 1

Did you search for this error message in this forum already. The suggestions are always the same:

• Free memory that is not longer in use, see clear
• Close otehr programs
• Install more RAM
• Check for bugs
• Check the sizes of the concerned variables

Do you really want

a = deltav / deltat;

or should this be an elementwise division:

a = deltav ./ deltat;
