How can I assign strings from array to variable name from another array with same size?

There are two arrays with the same size. Bothe arrays are filled with strings. The target is to use the strings from the first array as variable names and the strings from the other array as values in form of string. This means to assign first string from the other array to the first string from the first array and the second string from the other array to the second string from first array.

Target as example:

calbelength = long

cablecrosssection = small

fuseboxname = FuseBox2

Matlab Code:

Matrix_parameter_string = ["calbelength","cablecrosssection","fuseboxname"]
Matrix_value_string = ["long","small","FuseBox2"]
[line,coloumn] = size(Matrix_parameter_string)
p = coloumn;
for t = 1:p
   eval(fprintf('%s=%s',Matrix_parameter_string(1,t),Matrix_value_string(1,t))); % Assign value to parameter name
end

Matlab shows following error in command window:

calbelength=longError using eval

Must be a string scalar or character vector.

Error in Untitled (line 6)

eval(fprintf('%s=%s',Matrix_parameter_string(1,t),Matrix_value_string(1,t))); % Assign value to parameter name

By the way, if the values are double instead string. This would be the solution:

for t = 1:p
   eval(sprintf('%s=%d;',Matrix_parameter_string(1,t),Matrix_value_double(1,t))); % Assign value to parameter name
end

You forgot the quote in your right side assignement

Matrix_parameter_string = ["calbelength","cablecrosssection","fuseboxname"];
Matrix_value_string = ["long","small","FuseBox2"];
[line,coloumn] = size(Matrix_parameter_string);
p = coloumn;
for t = 1:p
   eval(sprintf('%s="%s"',Matrix_parameter_string(1,t),Matrix_value_string(1,t))); % Assign value to parameter name
end

Thank you very much for your solution for this task
