2D Line Interpolation(MORE)

Hi

First of all Thanks KSSV

I need some more help. As answered by KSSV

data = [36.97  126.5  36.79  126.45  394.94  1.79

 y1 = data(:,1) ; y2 = data(:,3) ; 
 x1 = data(:,2) ; x2 = data(:,4) ;
val = data(:,5) ; err = data(:,6) ; 
m = 100 ; 
xi = linspace(min(x1),max(x1),m) ;  
yi = linspace(min(y1),max(y1),m) ;  
[X,Y] = meshgrid(xi,yi) ; 
V = griddata(x1,y1,val,X,Y) ; 
pcolor(X,Y,V)
shading interp

Its working

I need more help

>>>>>> Need grid nodes values (each nod's value)

Thanks for your kind help.

Waiting

What do you mean by? Need to consider errors as standard error for each value "err"

Need grid nodes values (each nod's value)

Already you have this for each X, Y you have respective V.

[John D'Errico]

Interpolation, since that is what you are asking about, has nothing to do with any assessment of error in your data. An interpolant always passes exactly through the data provided, so any errors are irrelevant.

[Muhammad Zafar Iqbal]

Dear John/KSSV

Error is important for interpolation as like I want to clear as in a cell

you can see the impact of error.

Also,

The figure looks like the cell value is distributed equally while in fact the cell value is dependent upon the contridution. like (just for example)

Thats why I am asking about the node values

I hope you can understand my asking.

Thanks
