I wrote the following function so that I can use the structure 'stormdata' into another function. But matlab is assigning my data into ans instead of stormdata. What is going on here??

function stormdata = readstormdata(mystormdata)

load mystormdata.dat,

[rows, cols] = size(mystormdata);

for i = 1:rows

        stormdata(i) = struct('location',mystormdata(i,1),'inches',...
        mystormdata(i,2),'hours',mystormdata(i,3),'intensity',...
        mystormdata(i,2)/mystormdata(i,3));)/mystormdata(i,3);

end

The question is not clear: Where in the posted code does the variable "ans" appear?

How do you call your function? Like this:

stormdata = readstormdata(mystormdata)

Then it looks strange, that "mystormdata" is the input variable and the name of the .dat file. It is smarter to catch the output of load in a variable, because e.g. the readers in the forum cannot guess, what is written magically to the worksapce by this load.
