How to interpolate data in cells?

2 views (last 30 days)
I have data concentrated in 7x 1 cell (attached).
I want to interpolate each array to 100 data points using the following line
P_or_z_cycle = interpft(P_or_z_cycle, 100)';
which gives me an error:
Error using fft
Invalid data type. First argument must be double, single, int8, uint8, int16, uint16, int32, uint32, or logical.
Error in interpft (line 67)
a = fft(x,[],1);
How can I ovecome this please?

As follows:
S_or_x_cycle2 = cellfun(@(x) interpft(x,100), S_or_x_cycle, 'uni', 0)
