Hello, I am working with matrices and need to monitoring in some steps the info of the matrix, but sometimes instead of having a complete answer, the Matlab shows them with sigmas, like variables. I want to know if there is a way to modify the Matlab to always get the complete info in the matrices, without the sigmas.
For example:
syms E E1 E2 E3;
E1 = -1; E2 = 1; E3 = 0;
N1 = ((E-E2)/(E1-E2))*((E-E3)/(E1-E3));
N2 = ((E-E1)/(E2-E1))*((E-E3)/(E2-E3));
N3 = ((E-E1)/(E3-E1))*((E-E2)/(E3-E2));
b= [diff(N1,E) diff(N2,E) diff(N3,E)];
k= b.* b.'
This is what Matlab shows me:
I want to see the matrix with all the correct info, not with sigma variables.

Hi,
Which MATLAB version you are using?
On running your given code on MATLAB R2021a, I got following output:

You may be running your code in the live editor.
Running the code in a usual script or command window displays the result in the way you want.
Or
To display the results without being abbreviated, set 'AbbreviateOutput' preference to false.

Thank you for the answer.
sympref('AbbreviateOutput',false)
if you want to return to the original output display, then use sympref('default')
