Hi everyone,
I want to use for loop instead of just typing particular h values how can I do that ?.
Furthermore, my ta and tb got 3 elements whereas my tc got 11 elements and td got 21 elements, same as va vb vc vd respectively.
Thanks in advance

Please post your code as code instead of a picture. What exact function are you using? The only midpoint function I can find in the documentation is the Deep Learning Toolbox midpoint function, which has a different syntax.
Anyway, the stated problem itself is easily solved like this (I used cell due to the differently sized variables):
h=[0.7 0.5 0.1 0.05];
t=cell(1,numel(h));
v=cell(1,numel(h));
for k=1:numel(h);
[t{k},v{k}]=midpoint(dvdt,tspan,v0,h(k));
end

Firstly, thanks for helping.
I used your code, and it states that "Conversion to cell from double is not possible"

Then you will have to describe better what your function is doing. What is the input and output? I don't see how you could get that error with my code. Please attach your entire code as an m-file, or try to reduce it to a MWE so we can run your code without any other dependencies and can reproduce your issue.
