如何将matlab拟合函数应用于矩阵的每一行

for

I=imread('test.tif','tif');  
I=double(I);  
nat=num2cell(I,1);  
wy_I=cellfun(@size,nat, 'UniformOutput', false);  
we_I=cellfun(@(x)1:x(1), wy_I, 'UniformOutput', false);  
wyn=cellfun(@(x,y)fit(x',y,'fourier1'), we_I, nat);   

??? Error using ==> cellfun cfit type is not currently implemented.

wyn=cellfun(@(x,y)fit(x',y,'fourier1'), we_I, nat, 'UniformOutput',false);  

j=cell2mat(we_I(1,1))  
k=cell2mat(nat(1,1))  
z=fit(j',k,'fourier1')
