How to remove rows that do not contain or match a specific 'string'

What I am trying to do is remove rows in my cell array "Vars" that do not contain any of the values in the cell array "Names"

For example I have a an array of data ive created/imported

Vars=

'Subject' 'Mass' 'Height' 'Age'

'A' 90 170 20

'B' 100 182 20

'C' 85 180 21

'D' 80 185 21

'E' 79 175 20

But I only want a final array containing the values corresponding with the strings in the array "names"

Names=

'Subject'

'A'

'C'

'D'

So the final product should look like

FinalVars =

'Subject' 'Mass' 'Height' 'Age'

'A' 90 170 20

'C' 85 180 21

'D' 80 185 21

Thankyou in advance for your help,

Note** the string 'A', 'B' etc will most likely be a last name ie. 'smith' or 'john' etc.

Storing numeric scalars in a cell array makes processing that data much more difficult. Some beginners like the idea of storing any headers and footers together with their data in a cell array, but it is really much simpler to keep numeric data stored in a numeric array, and the headers and footers in their own cell vectors.

Alternatively you could use a table, which is exactly designed for data arranged like yours:

For a cell array you can use ismember:

Vars = {
'Subject' 'Mass' 'Height' 'Age'
'A' 90 170 20
'B' 100 182 20
'C' 85 180 21
'D' 80 185 21
'E' 79 175 20};
Names = {'Subject','A','C','D'};
idx = ismember(Vars(:,1),Names);
out = Vars(idx,:)
