Hello everyone,

I am trying to execute a code but it requires data matrix (605x1006x3) to be structure array. How can I convert the matrix into structure array? Here is how the data looks like.

Thanks in advance, Igor

period_1_allstocks.m

Hello,

James, thank you for your comment. James, the original code is attached. (period_1_allstocks.m) The exact error I get is the following.

period_1_allstocks
Error using rmfield (line 17)
S must be a structure array.
Error in period_1_allstocks (line 4)
cdata=rmfield(cdata, redundant);

This is basically the script which can be found here. http://nl.mathworks.com/matlabcentral/fileexchange/59541-pairs-trading-strategy-ggr--2006- The data we are going to use can be found below. We have to customize the script in order to analyze the data. Columns are individual stocks and rows are daily prices of differet stocks. http://www.filedropper.com/pricesraw

Walter, thank you for your comment. I am trying to convert it to the structure array because code error requires so in order to run the code. I am writing the research projects with my colleagues and we should test the findings of this code but for different data set - European stocks. We still cannot run the code with default CRSP data which is in an image format and from here I can conclude that our testing of the code on European stocks if far away.

Every help would be greatly appreciated. We did not have Matlab courses and our supervisor gives us almost no guidance, so we are trying to learn as we go.

Thanks once again.

Best, Igor

That pricesraw file has 4000 rows of 600 columns, but no headers. I cannot tell what each column corresponds to.

Hi Walter,

Thanks for helping me. Columns are individual stocks[600 stocks] and rows are the dates. It is basically data panel with 600 stock returns over seventeen year period. I hope that it clarifies the data.

Thanks, Igor
