Yes.
Let us use an example:
x=1:10; % Data Set
z=1:20; % Range
y=x^2; % Equation
equation1=trapz(y,z) % This will integrate y over the range of z for your data
When integrating over a matrix:
x2=[ 1 2 3; 4 5 6]; % Matrix
y2=x*C; % Where c is any variable
equation2=trapz(y2);
% Will integrate over every column of your matrix and give you an array.
To calculate a double integral using the trapz function in MATLAB, you can first create a grid of points for the two variables you are integrating over. Then, evaluate the function you are integrating at these points to create a matrix of function values. Finally, use the trapz function twice - once along one dimension and then along the other dimension - to compute the double integral.
Trapz of Poetic Poison was created in 1996.

There are plenty of them that are used to produce the action of walking, but mainly the muscles of the lower extremities do most of the work. These include the quadriceps, hamstrings, adductors, gastrocnemius, and soleus. The joints used are the iliofemoral (hip) joint, the tibiofemoral (knee) joint, and the talocrural (ankle) joint.
