sort a string based on particular value

Hello All,

i have a list of type

ch = { 'temp_25_vgs_8', 'temp_25_vgs_3', 'temp_25_vgs_9', 'temp_25_vgs_10', 'temp_20_vgs_8', 'temp_20_vgs_5', 'temp_25_vgs_5'};

i need to sort it based on vgs value (or both vgs and temp) and get back the list as

ch = { 'temp_20_vgs_5',

'temp_20_vgs_8',

'temp_25_vgs_3',

'temp_25_vgs_5',

'temp_25_vgs_8',

'temp_25_vgs_9',

'temp_25_vgs_10'

} ;

please help me resolve that,

than you in advance

Hi Sajid,

The sort function with the arrayfun can be used to check this.

chs = arrayfun(@(x) str2double(string([ch{x}(5+1:8-1) ch{x}(13:end)])),1:numel(ch))
[~,i] = sort(chs);
out = ch(i);

Hope this helps.

Regards,

Sriram

Hello Sriram,

it is only taking temp into consideration.

i need it to get sort based on vgs value also

K 
K>> sort(ch)'

ans = 

    'temp_20_vgs_5'
    'temp_20_vgs_8'
    'temp_25_vgs_10'
    'temp_25_vgs_3'
    'temp_25_vgs_5'
    'temp_25_vgs_8'
    'temp_25_vgs_9'

Hi Sajid,

Here is what you are looking for, if you know what the index locations are already, then you perform something as such:

chs = arrayfun(@(x) str2double(string([ch{x}(5+1:8-1) ch{x}(13:end)])),1:numel(ch))
[~,i] = sort(chs);
out = ch(i);

To find the locations exactly which has the starting numbers, you can use this

ind = regexp(ch,'_'); % it provides index in each cell

Let me know if this helped.

Thanking you.

Regards,

Sriram
