memory - variable becomes undeclared after some iteration in matlab -

this question has answer here:

• is possible have workspace variable persists across call clear? 2 answers

does matlab keep variables after clearing?

matlab: free memory lost after calling function

my question related post changes there.

i have use output (the outputs matrices generated, i.e. generating small matrices in every iteration) produced previous large program, in next iteration of large program, when using technique mentioned in post, getting error " reference cleared variable", need keep of variables , matrices generated. how that?

sometimes error occurs after 1 iteration

thanks

you can clear specific variables in workspace with:

clear myvarname 

you can clear functions might holding persistent variables with:

clear myfunname 

so - should work out ones don't want (type whos see variables in workspace, or in breakpoint) , clear ones don't need.

another option save ones want, use clear method mentioned, re-load.
