Viewing Symbolic Matrix Entries in Variable Tab?

Is there a way to view a symbolic matrix in the variable tab instead of the command window? I know I can view it in the command window, but for a larger matrix columns move down into rows and is not a great UI. When opening variable view this is how it displays symbolic entries:

I can only see each entry after double clicking into it. Is there a view option to see the actual equations from the above screen?

Applications are primarily a Jacobian Matrix or any matrix equation with a matrix of derivatives used for numerical methods. I like to symbolically solve the derivative matrix, then use those derived equations in the iteration loop therafter to reduce compilation time by only differentiating once. Viewing the results is a nice sanity check.

Any tips are appreciated. -Charlie

No, No there is no way to do that.

If you

temp = arrayfun(@char, YourSymArray, 'uniform', 0);
openvar temp

then you will be able to see roughly the first 10 characters of each entry (unless you drag the edges to make the entries wider)

Great workaround, thanks!

I now use this same concept in a function for viewing complex numbers in polar form in one go. Thanks again.

If you're planning to use the symbolic expression in a loop you may want to create a MATLAB function file from it using matlabFunction. You could read the generated code as a check that the expression you're evaluating is what you expect it to be.

This is actually what I had first tried. My function was supposed to accept one variable t, and a vector of values x for each iteration. Converting the entire symbolic matrix equation to a function via matlabFunction resulted in the symbolic x values being distributed throughout (reshaping/simplifying the matrix equation when matlabFunction was called). Therefore, I could not pass in the vector as one variable x in the function handle.

I am sure there is a workaround as I had not implemented matlabFunction prior. I will investigate its use again in the future and try again. Thank you for confirming that it should work and is a good option. It would be my prefered method for speed and readability purposes.
