Subextract data from a matrix

Dear all,

I'm trying to plot some satellite data with matlab, in which I would like to subset my interest area. The problem I'm having is to subset the matrix that contains my data. I've a 3250x1325 matrix of data, and a 3250x1 vector for lon and 1325x1 for lat. Does anyone has an idea how can I subset my interest area from the data matrix?

Thanks for the help.

Cheers

Joao

latmatches = (lat >= LowerLatBound & lat <= UpperLatBound);
longmatches = (long >= LowerLongBound & long <= UpperLongBound);
datasubset = YourMatrix(longmatches, latmatches);

[Walter Roberson]

You say that your matrix is 3250 x 1325, and that your lon vector is 3250 x 1. That implies that the first index in to your matrix is lon. The error message you show uses lat as the first index of the matrix.

I'm realy sorry. Your answer is correct.

The problem was some lines above i was using meshgrid to generate a grid to plot my SST values. I manage now to subextract my study area.

Thanks very much for your help.

Best regards
