Hi I am working on a matlab program that solves a few differential equations to find the results of a heat transfer problem.

I have the differential portion completed but I am having trouble printing out the data to a table

options= odeset('RelTol',1e-6,'AbsTol',[1e-6 1e-6]); [t,M]= ode45(@dMdt_project4_66,tspan,initialvalues,options);

where dt= 0.1; dmax=70; dmin= 0; tspan= dmin:dt:dmax;

I want to print the results every second into a table. Any suggestions? ODE45 help doesnt explain.

Thank you

With your tspan, if you define ‘tp’ as the times you want to plot and ‘Mp’ as the ‘M’ values you want to plot:

tp = tspan(1:10:end);
Mp = M(1:10:end);
