Error assigning variable in loop

It is beyond me why I cannot figure this out. The debugger points to the line 'wsstd(i,1) = fricvelo.*4;' but I think it has to do with my if statement as even when the condition is failed, a calculation is still done. L(1,1) for instance is -0.393. I am sure my tired eyes just can't find the simple problem.

wsstd = zeros(length(ws),1);

for i = 1:11950;

      if L(i,1) >= -500 && L(i,1) <= -50
          wsstd(i,1) = fricvelo.*4;
      else
          wsstd(i,1) = 0;
      end

end

1. Please post the exact and complete error message.
2. What is the result of typing size(fricvelo) at the command prompt?

Hi Rick,

Here is the message:

Subscripted assignment dimension mismatch.

Error in ERA_Suomi_parametrization (line 43)
        wsstd(i,1) = 

43          wsstd(i,1) = fricvelo.*4

size(fricvelo) is (39928,1) where the #rows is the same as the length(ws)

You're trying to insert a 39928x1 vector in only one element of wsstd.

size(wsstd(i,1)) == 1 for any i.

So you have a dimension problem.

you can only put a scalar in wsstd(i,1).

You need to change something (like fricvelo(i) ?...)

Wow! How did I not see such an obvious answer! Sorry for waste of time Orion. Thanks
