Evaluate string as input keyword in matlab

How to evaluate a string which could be changed dynamically in code? for example:

A=rand(60, 60);
RangeC='10:end,:';
B=A(RangeC);

I know this is quite easy for others, but I have struggled for hours! Thanks in advance!

You can use the eval function but I would suggest to seperate RangeC in two variables like the example below. Also end won't be able to be evaluated so you can use size instead.

A=rand(60, 60);
RangeC1='10:size(A,1)';
RangeC2='1:size(A,2)';
B=A(eval(RangeC1), eval(RangeC2));
