How can i sort matrix (all rows) according to specific colums?

Hi,

I would order a matrix according on values in specific columns.

My matrix is T = [[DICTIONARY.IC.len DICTIONARY.IC.vx DICTIONARY.IC.vy DICTIONARY.IC.vz DICTIONARY.IC.ox DICTIONARY.IC.oy DICTIONARY.IC.fiber]

where DICTIONARY.IC.xxx are column vectors.

I would like sort it according on the values of DICTIONARY.IC.vx DICTIONARY.IC.vy DICTIONARY.IC.vz and i use the command:

Tsort = sortrows (T, [2 3 4]);

but obtain the following error:

??? Error using ==> sortrowsc Out of memory. Type HELP MEMORY for your options.

Error in ==> sortrows at 74 ndx = sortrowsc(x_sub, col);

Error in ==> main at 43 Tsort = sortrows (T, [2 3 4]);

Why?

Thanks, Davide

'Cuz T is quite large, most likely and you've got multiple copies?

Try

clear DICTIONARY

first after creating the array and see if that will give you sufficient memory to proceed.
