Error using interp1

I am trying to do an optimization with values generated from abaqus. But I am struggeling to adjust my sample size so it matches my experimental data.

[unique_expperimental_dis, index] = unique(xlsread('Tensile_test_45_exp_avg.xlsx','A:A'));

exp_data = xlsread('Tensile_test_45_exp_avg.xlsx','B:B');

unique_experimental_force = exp_data(index,1);

abaqus_force_interp= interp1(unique_expperimental_dis,unique_experimental_force,abaqus_results(:,1));

Error using interp1>reshapeAndSortXandV (line 424)

X and V must be of the same length.

Thanks for any help.

The error is straightforward — the first and second argument vectors must be the same length. They can be different sizes, so one can be a row vector and the other a column vector, however they must have the same numbers of elements.

From your code, it appears that they should be, so we would have to have your data to see what the problem is.
