I have a cell array which its elements contain both number and characters.
    ["LAN310"]
    ["SHA550"]
    ["SHA430"]
    ["SHB331"]
    ["EDU110"]
    ["IFE101"]
    ["BSM110"]
    ["BSM310"]
    ["BSM540"]
    ["LAN121"]
    ["LAN330"]
    ["IFE151"]
    ["IFE111"]
    ["BSM170"]
    ["BSM320"]
    ["BSM550"]
    ["LAN132"]
    ["SHB492"]
    ["EDU251"]
    ["IFC130"]
    ["IFC170"]
    ["CCT891"]
    ["IFC291"]
    ["IFC121"]
    ["BSM191"]
    ["SHB451"]
    ["TAM160"]
    ["EDU210"]
    ["IFC180"]
    ["IFC150"]
    ["IFC161"]
    ["IFC200"]
    ["IFC301"]
    ["EDU220"]
    ["EDU180"]
    ["IFC431"]
    ["IFC240"]
    ["IFC250"]
    ["IFC311"]
    ["IFC210"]
    ["IFC190"]
    ["TAM111"]
    ["EDU820"]
    ["IFC441"]
    ["IFC353"]
    ["IFC260"]
    ["IFC421"]
    ["IFC411"]
    ["BSM790"]
    ["SHB242"]
    ["EDU261"]
    ["EDU201"]
    ["IFC451"]
    ["IFC224"]
    ["IFE130"]
    ["IFC373"]
    ["IFC363"]

    ["IFC330"]
    ["BSM461"]
    ["IMA262"]
I want to remove the " and numbers from my cell and I want the characters to remain only so it becomes like this :
    [LAN]
    [SHA]
    [SHA]
    [SHB]
    [EDU]
    [IFE]
    [BSM]
    [BSM]
    [BSM]
    [LAN]
    [LAN]
    [IFE]
    [IFE]
    [BSM]
    [BSM]
    [BSM]
    [LAN]
    [SHB]
    [EDU]
    [IFC]
    [IFC]
    [CCT]
    [IFC]
    [IFC]
    [BSM]
    [SHB]
    [TAM]
    [EDU]
    [IFC]
    [IFC]
    [IFC]
    [IFC]
    [IFC]
    [EDU]
    [EDU]
    [IFC]

    [IFC]
    [IFC]
    [TAM]
    [EDU]
    [IFC]
    [IFC]
    [IFC]
    [IFC]
    [IFC]
    [BSM]
    [SHB]
    [EDU]
    [EDU]
    [IFC]
    [IFC]
    [IFE]
    [IFC]
    [IFC]
    [IFC]
    [IFC]
    [BSM]
    [IMA]
Can someone please guide me how to do this?
Thanks

A trivial implementation using regexprep:
D = regexprep(C,'[\d"]','');
And tested:
>> C = {'["LAN310"]';'["SHA550"]';'["SHA430"]';'["SHB331"]';'["EDU110"]', ... };
>> D = regexprep(C,'[\d"]','');
>> D{:}
ans = [LAN]
ans = [SHA]
ans = [SHA]
ans = [SHB]
ans = [EDU]
... etc
