i have a variable in my workspace and i dont know its name directly

for example i have loaded a variable

Verification_2018 = [ ];

in my workspace. now i directly dont know its name. i know that starting part would be "verification " but the year may change which i can get from another struct.

i.e struct.filename contains the name 'Verification_2018'

now using this name i am having trouble accessing the variable loaded in the workspace.

how can we do that

thanks in advance

"now using this name i am having trouble accessing the variable loaded in the workspace"

Forcing meta-data (e.g. the year) into variable names is a sign that you are doing something wrong.

Rather than forcing yourself into writing slow, complex, buggy, difficult-to-debug code, you should load the file data into an output variable, and then you can avoid this situation entirely.

If you have variables in the workspace....to get the variable names use:

S = whose ;
names = {S.name} ; 

Use strcmp to find whether your variable is present or not. Read about strfind as well.

 S = whos

Do not load directly into the workspace, always load into an output variable (which is a scalar structure):

S = load(...);

Then you can efficiently access all of its fields e.g. using fieldnames and dynamic fieldnames:

If there is exactly one variable in the mat file (but you don't know its name) then you can simply access it like this:

C = struct2cell(S);
A = C{1};
