Error in my code : Array dimensions must match for binary array op. Error in newhet (line 139) lamd4=20*D​3-30*D2+12​*D1-D0;

This is the code

C0=nansum(c0,2);

lamc1=C0;

C1=nansum(c1,2);

lamc2=2*C1-C0;

C2=nansum(c2,2);

lamc3=6*C2-6*C1+C0;

C3=nansum(c3,2);

lamc4=20*C3-30*C2+12*C1-C0;

The above same code is running but the error is coming in higlighted portion.

D0=nansum(d0,2);

lamd1=D0;

D1=nansum(d1,2);

lamd2=2*D1-D0;

D2=nansum(d2,2);

lamd3=6*D2-6*D1+D0;

D3=nansum(c3,2);

lamd4=20*D3-30*D2+12*D1-D0;

Hi Namrata

In the second last line, it says:

D3=nansum(c3,2);

Judging by the code above the given line, it seems to be a typo, and the correct code should use d3 instead of c3:

D3=nansum(d3,2);

Using c3 instead of d3 should be the reason for mismatch in array dimensions, assuming C0 and D0 have different dimensions to begin with.

Hope this helps
