how to solve "Subscripted assignment dimension mismatch"?

time_roi = [0 30];
intind_p = find(t >= 0 & t <=30);
H_roi = squeeze(newdcAvg(intind_p,1,:,:));
peak_h=squeeze(max(H_roi,[],1));
t_roi=t(intind_p);
for i=1:size(peak_h,1);
    for j=1:size(peak_h,2);
        t_ind = squeeze(H_roi(:,i,j));
        peak = peak_h(i,j);
        position= find(t_ind == peak_h(i,j));
        p_latency(i,j)=[t_roi(position)];
    end
end

I guess "p_latency(i,j)=[t_roi(position)];"might be wrong,but i dont know how to change it.

Thank you. the codes below are where i get "Subscripted assignment dimension mismatch“ ， and if i imput just numbers, it can run smoothly. So i guess "p_latency(i,j)=[t_roi(position)]" might need modification, and i seek for the help here.

for i=1:size(peak_h,1);

for j=1:size(peak_h,2);

t_ind = squeeze(H_roi(:,i,j));

peak = peak_h(i,j);

position= find(t_ind == peak_h(i,j));

p_latency(i,j)=[t_roi(position)];

end

end

Most likely the value of [t_roi(position)] is not a scalar. Since I cannot run the code, I cannot say for sure. Put a break-point at the line and inspect the value of [t_roi(position)]

[Wenbo]

Thank you! Here, t_roi(position) is a number.

Show us all the variables and full code, so that we can help you.

"a number" that shouldn't cause this error. I don't understand.

It may be that position= find(t_ind == peak_h(i,j)) finds more than one, which wouldn't be compatible with p_latency(i,j)=[t_roi(position)]. In fact why do you have brackets in this line?
