%一維插值函數(shù)，用于質(zhì)心、轉(zhuǎn)動(dòng)慣量及推力的插值，輸入變量依次為：待插參數(shù)數(shù)組，插值點(diǎn)時(shí)間值
function W = oneinterp1(t1,t2)
[x y]=size(t1);

if t2<=t1(1,1)%時(shí)間小于或者等于最小給定時(shí)間值
    j=1;
end    

if t2>t1(x,1)%時(shí)間大于最大給定時(shí)間值
    j=x-1;
else
     j=1;
     while t2>t1(j+1,1)
          j=j+1;
     end    
end     

W=t1(j,2)+(t1(j,2)-t1(j+1,2))*(t2-t1(j,1))/(t1(j,1)-t1(j+1,1));
