I am trying to make a comparison between the minutes value of the time from two tables using the following lines
first we checck if the dates are matching then we check if the value of the minutes in t2 satisfy the following:
minute of t2-30mins<=minute of t2<=minute of t2+30mins
[Lia2, Locb2] = ismember(t1.Date3, t2.date2);
indx2 = Locb2(Locb2 > 0);
% Tminu = '30:00';
% infmt = 'mm:ss';
% Dminu = duration(Tminu,'InputFormat',infmt);
t2.minsubtract30=minute(t2.date)-minutes(30);
t2mins=minute(t2.date);
if ( t2mins(indx2)>= t2.minsubtract30 && t2mins(indx2)<= t2.minadd30)
t1.foF2(Lia2)=t2.fof2(indx2);
if m==1
datatable=t1;
else
datatable=[datatable; t1];
end
end
but I am getting the following error
perands to the logical and (&&) and or (||) operators must be convertible to logical scalar values.
Error in Ionosonde_Data (line 112)
if ( t2mins(indx2)>= t2.minsubtract30 && t2mins(indx2)<= t2.minadd30)

It's better to attach your data and full code.

try this
all(condition1)&&all(condition2)
