how to use workspace data and run the matlab ?

Hello I have mat file which contains data and i have written a matlab script.

for example

a= [1.021 -685.1 0 0;1 -0.5 0.02222 0;0.4228 0 -1.111 -0.4444;0.4228 0 01.556]

b=[140.2 0; 0 0; 0 1;0 1];

c=[9.55 0 0.2122 0; 0 0 0 0.4444];

d=zeros(2);

this is my inputs in the code but i have another *.mat file which contain data about a,b,c,d and i want to use this data and run the script.

how should i do this ?

Do not import the variables directly, because overwriting locally existing variables can cause errors, but store the output of load in a struct:

DataFromFile = load('YourFile.mat');
perhaps = a - DatafromFile.a

you can save your data, then use load when you need them
